| 1 | The mixing of multi-source fluids in the Wusihe Zn–Pb ore deposit in Sichuan Province, Southwestern China显示文摘The Sichuan-Yunnan-Guizhou(SYG)metallogenic province of southwest China is one of the most important Zn-Pb ore zones in China,with^200 Mt ZnPb ores at mean grades of 10 wt.%Zn and 5 wt.%Pb.The source and mechanism of the regional Zn-Pb mineralization remain controversial despite many investigations that have been conducted.The Wusihe Zn-Pb deposit is a representative large-scale Zn-Pb deposit in the northern SYG,which mainly occurs in the Dengying Formation and yields Zn-Pb resources of^3.7 Mt.In this paper,Zn and S isotopes,and Fe and Cd contents of sphalerite from the Wusihe deposit were investigated in an attempt to constrain the controls on Zn and S isotopic variations,the potential sources of ore-forming components,and the possible mineralization mechanisms.Both theδ66Zn andδ34S values in sphalerite from the Wusihe deposit increase systematically from the bottom to the top of the strata-bound orebodies.Such spatial evolution inδ66Zn andδ34S values of sphalerite can be attributed to isotopic Rayleigh fractionation during sphalerite precipitation with temperature variations.The strong correlations between the Zn-S isotopic compositions and Fe-Cd concentrations in sphalerite suggest that their variations were dominated by a similar mechanism.However,the Rayleigh fractionation mechanism cannot explain the spatial variations of Fe and Cd concentrations of sphalerite in this deposit.It is noted that the bottom and top sphalerites from the strata-bound orebodies document contrasting Zn and S isotopic compositions which correspond to the Zn and S isotopic characteristics of basement rocks and host rocks,respectively.Therefore,the mixing of two-source fluids with distinct Zn-S isotopic signatures was responsible for the spatial variations of Zn-S isotopic compositions of sphalerite from the Wusihe deposit.The fluids from basement rocks are characterized by relatively lighter Zn(~0.2‰)and S(~5‰)isotopic compositions while the fluids from host rocks are marked by relatively heavier Zn(~0.6‰)and S(~15‰)isotopic compositions. | Hongjie Zhang Haifeng Fan Chaoyi Xiao Hanjie Wen Lin Ye Zhilong Huang Jiaxi Zhou Qingjun Guo | 2019 | Acta Geochimica2019，38，5： | 6 |

| 3 | 2-4 First Isochronous Mass Measurement in Neutron-rich Region at CSRe显示文摘Mass is one of the fundamental properties of atomic nuclei. Isochronous mass spectrometry (IMS), using astorage ring combined with an in-flight separator, has been shown to be a powerful tool for mass measurementof exotic nuclei[1]. Recently, masses of many proton-rich nuclides were accurately determined at the HIRFL-CSRfacility[2]. In this paper, we described the first isochronous mass measurement of neutron-rich nuclides at CSRe.This experiment was performed at the end of 2011. In the experiment, the primary beam of 86Kr28+ ions wasaccumulated and accelerated to an energy of 460.65 MeV/u in the synchrotron CSRm. The 86Kr28+ ions were fastextracted and focused on a 15 mm thick beryllium target which was placed at the entrance of the RIBLL2 (anin-flight fragment separator). | Xu Xing Wang Meng Zhang Yuhu Xu Hushan Tu Xiaolin Yu.A.Litvinov Zhou Xiaohong Sun Baohua Yuan Youjin Xia Jiawen Yang Jiancheng K.Blaum Chen Ruijiu Chen Xiangchen Fu Chaoyi Ge Zhuang Hu Zhengguo Huang Wenjia Liu Dawei Y.H.Lam Ma Xinwen Mao Ruishi T.Uesaka Xiao Guoqing Xing Yuanming T.Yamaguchi Y.Yamaguchi Zeng Qi Yan Xinliang Zhao Hongwei Zhao Tiecheng Zhang Wei Zhan Wenlong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 4 | 2-6 First Isochronous Mass Measurements with Two Time-of-Flight Detectors at CSRe显示文摘In conventional isochronous mass spectrometry (IMS), single time-of-flight (TOF) method is adopted to measurethe ions' revolution times in a storage ring which can then be used to calculate the ions' masses. However, themass-to-charge ratio (m=q) is only related to the revolution time (T) under the condition that is equal to taccording to the following equation: | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Shuai Peng Xu Xing Chen Ruijiu Yan Xinliang Tu Xiaolin Zhang Wei Fu Chaoyi Zeng Qi Yu.A.Litvinov K.Blaum Chen Xiangcheng Ge Zhuang Gao Bingshui Huang Wenjia S.A.Litvinov Liu Dawei Ma Xinwen Mao Ruishi Xiao Guoqing Yang Jiancheng Yuan Youjin Zhou Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 5 | 2-9 Half-life Measurement of 94mRu44+ at CSRe显示文摘A radioactive nucleus is characterized with an intrinsic half-life. However, for a nuclear species, the half-lives inneutral atoms could be very different from that in highly charged ions. The half-lives of some highly charged ionshave been directly measured at GSI for multiple motivations[1]. In the same case, the nuclear state(i:e the isomer)may be in the range of several tens of microseconds and their half-live can be measured using isochronous massspectrometry. The J = 8+ isomeric state in 94Ru was chosen to test this method. The half-life of this isomer is71 s [2] in neutral atoms, and the excitation energy is 2.64 MeV. The internal conversion coefficient of this decayin neutral atom is 0.335. So its half-life in the bare nucleus would be modified to be 94.78 s when the internalconversion channel is blocked. | Zeng Qi Zhang Yuhu Wang Meng Xu Hushan Tu Xiaolin Zhou Xiaohong Yan Xinliang Chen Ruijiu Huang Wenjia Ge Zhuang Liu Dawei Fu Chaoyi Sun Mingze Mei Bo Xu Xing Xing Yuanming Shuai Peng Zang Yongdong Zhang Wei Xiao Guoqing Yu.A.Litvinov Isao.Tanihata | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |

| 7 | 2-5 Mass Measurements of Neutron-defcient Nuclides 79Y,81,82Zr,83,84Nb显示文摘The masses of neutron-defcient nuclides play a critical role in the calculation of astrophysical rapid proton-capture processes[1].Neutron-defcient nuclides with mass number∧around 80 are the last set of nuclides with unknown masses on the pathway of vp-process[2].The mass measurement of nuclides would be very useful.In 2016,masses of neutron-defcient nuclides 79Y,81Zr,82Zr,83Nb and 84Nb nuclei were precisely measured directly by the experimental storage-ring CSRe at Lanzhou. | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Chen Ruijiu Shuai Peng Yan Xinliang Fu Chaoyi Xu Xing Tu Xiaolin Zhang Wei Zeng Qi Yu.A.Litvinov K.Blaum Chen Xiangcheng Ge Zhuang Gao Bingshui Huang Wenjia S.A.Litvinov Ma Xinwen Mao Ruishi Xiao Guoqing Yang Jiancheng Yuan Youjin Zhou Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 8 | 2-6 Mass Prediction of Neutron-defcient N=Z Nuclides 78Y,80Zr,82Nb and 84Mo显示文摘We have reported the mass measurements of neutron-deficient nuclides 79Y,81;82Zr,83;84Nb in this year’s Annual Report.However,for the N=Z nuclides close to A=80,the yield is much lower and even if they can be produced,there is still great difficult to identify them because of their quite similar mass-to-charge ratio and revolution times.However,their mass are extremely important for rapid proton capture process,for example,80Zr and 84Mo are waiting points of rp-process.Their masses can greatly effect the reaction flow of proton capture on them and then the abundance of the heavier nuclides.In addition,the separation energy of 84Mo(determined by the mass of 80Zr and 84Mo)has a strong impact on the 83Nb(p,α)reaction rate and plays a key role in the formation of Zr-Nb Fig. | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Chen Ruijiu Chen Xiangcheng Fu Chaoyi Ge Zhuang Gao Bingshui Huang Wenjia Ma Xinwen Mao Ruishi S.A.Litvinov Shuai Peng Tu Xiaolin Xiao Guoqing Xu Xing Yan Xinliang Yu.A.Litvinov Yang Jiancheng Yuan Youjin Zhang Wei Zeng Qi Zhou Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 9 | 2-7 Study of Zr-Nb Cycle in Astrophysical rp-process显示文摘At a certain high temperature,this cycle will be dominant and end the rp-process to heavier region[2].It provides an upper temperature limit for rp-process along the proton drip line to produce nuclides beyond A=84,including the light p nuclides of 92;94Mo,96;94Ru.The existence of Zr-Nb cycle is an important question in rp-process[2].α-separation energy(Sα)of 84Mo plays an important role in the formation of this cycle.A strong enhancement of 83Nb(p,α)reaction rate is due to a very low Sαof 84Mo[1]. | Xing Yuanming Zhang Yuhu Wang Meng Li Kuoang Tang Xiaodong Xu Hushan Chen Ruijiu Chen Xiangcheng Fu Chaoyi Ge Zhuang Gao Bingshui Huang Wenjia Ma Xinwen Mao Ruishi S.A.Litvinov Shuai Peng Tu Xiaolin Xiao Guoqing Xu Xing Yan Xinliang Yu.A.Litvinov Yang Jiancheng Yuan Youjin Zhang Wei Zeng Qi Zhou Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
