| 1 | β-decay Study of Tz=-3/2Proton-rich Nucleus 29S显示文摘The exotic decay of nuclei far from the stability has recently become a hot topic of nuclear structure research.The nuclide 29S is not well investigated in the A=4n+1,Tz=-3/2series of strong+β-delayed proton precursors.The decay schemes of these nuclei are characterized | ZHONG Fupeng XU Xinxing LIN Chengjian WANG Jiansong LI Zhihuan YANG Lei MA Nanru WANG Dongxi WEN Peiwei SUN Lijie WU Hongyi LUO Diwen WU Chenguang JIANG Ying LIU Yang ZANG Hongliang LIANG Pengfei LI Pengjie LI Xiaojing ZHAO Qingqing SHI Guozhu MA Junbing MA Peng YU Gongming Dipikap Patel BAI Zhen YANG Feng JIA Huiming ZHANG Huanqiao WANG Jianguo YANG Yanyun MA Weihu HU Qiang JIN Shuya ZHOU Xiaohong LI Ren HOU Dongsheng LIU Minliang HU Zhengguo MA Xinwen YANG Weiqing GAO Zhihao DUAN Fangfang YU Yuechao WANG Yufeng WANG Peng ZHOU Qingwu CUI Danteng WANG Xiang HU Liyuan PAN Min ZHANG Gaolong WANG Xiaoyu | 2017 | Annual Report of China Institute of Atomic Energy2017，，1： | 0 |
| 2 | Differentiation of Algal Blooms and Aquatic Vegetation in Chinese Lakes Using Modified Vegetation Presence Frequency Index Method显示文摘Algal blooms in lakes have become a common global environmental problem. Nowadays, remote sensing is widely used to monitor algal blooms in lakes due to the macroscopic, fast, real-time characteristics. However, it is often difficult to distinguish between algal blooms and aquatic vegetation due to their similar spectral characteristics. In this paper, we used modified vegetation presence frequency index(VPF) based on Moderate-resolution Imaging Spectroradiometer(MODIS) imagery to distinguish algal blooms from aquatic vegetation, and analyzed the spatial and temporal variations of algal blooms and aquatic vegetation from a phenological perspective for five large natural lakes with frequent algal bloom outbreaks in China from 2019 to 2020. We simplified the VPF method to make it with a higher spatial transferability so that it could be applied to other lakes in different climatic zones. Through accuracy validation, we found that the modified VPF method can effectively distinguish between algal blooms and aquatic vegetation, and the results vary from lake to lake. The highest accuracy of 97% was achieved in Hulun Lake, where the frequency of algal outbreaks is low and the extent of aquatic vegetation is stable, while the lowest accuracy of 76% was achieved in Dianchi Lake, which is rainy in summer and the lake is small. Analyses suggests that the time period when algal blooms occur most frequently might not coincide with that when they have the largest area. However, in most cases these two are close in terms of time period. The modified VPF method has a broad scope of application, is easy to implement, and has a high practical value. Furthermore, the method could be established using only a small amount of measured data, which is useful for water quality monitoring on large spatial scales. | PU Jing SONG Kaishan LIU Ge WEN Zhidan FANG Chong HOU Junbing LV Yunfeng | 2022 | Chinese Geographical Science2022，32，5： | 0 |
| 3 | 通过^(1)H(^(15)O,p)^(15)O弹性散射来研究^(16)F的能级性质显示文摘The understanding of open quantum systems in unbound nuclei is a challenge to the nuclear structure research[1].The continuum coupling effect may lead to a reordering of the shells in such systems[2].A way to study this effect is to compare the level schemes of two mirror nuclei involving an unbound and a bound nucleus such as 16F and 16N[3].Here we report an experiment of studying the level properties of 16F using the resonant elastic scattering with an 15O radioactive beam delivered by the Radioactive Ion Beam Line at Lanzhou(RIBLL)[4]. | Ru Longhui Hu Jun Liu Enqiang Bai Zhen Duan Fangfang Fang Xiao Hou Suqing Hu Qiang Ji Liancheng Jin Shuya Li Kuoang Li Yiyang Li Ruojie Ma Peng Ma Junbing Sun Xinxin Shi Guozhu Tang Xiaodong Wang Xinyu Wang Jiansong Wang Yufeng Wu Jiatong Xu Xiaodong Xu Shiwei Xin Wenyu Yang Kaiping Yang Yanyun NMichel | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
| 4 | 2-16 Experimental Study of 13N(α,p)16O at the Stellar Energies显示文摘The presolar SiC grains[1]carry the original stellar nucleosynthesis signature.Their isotopic anomalies compared to the sun are the strong constrains in the supernovae(SN)model calculations.The 15N-excess in some SiC-AB grains(12C/13C<10 and 14N/15N<272)is one of the challenges of core-collapse supernovae(CCSNe)models[2].Recently,Pignatari pointed out that the entrainment of H-rich material into the He shell before the SN explosion allows the coproduction of 13C,15N and 26Al,which provides a new production scenario for SiC-AB grains[2].In the He shell nucleosynthesis,the 13C is produced through 12C(p,γ)13N(β+γ)13C reaction.The 14N is synthesized through 13N(n,γ)and 13C(p,γ)reactions. | Lin Weiping Ma Shaobo Hu Jun Bai Zhen Chen Han Chen Zhijun Duan Fangfang Gao Bingshui Gao Zhihao Hou Suqing Ji Liancheng Jia Baolu Jiao Lei Jin ShuYa Liu Xingquan Li Kuoang Lu Tan Ma Junbing Ma Peng Tang Xiaodong Wang Xinyu Xu Shiwei Yang Yanyun Yu Gongming Yu Xiangqing Zhai Yaojie Zhang Ningtao Zhang Xing | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
