| 4 | 2-2 Complete and Incomplete Fusion of 9Be + 169Tm, 187Re at Near-barrier Energies显示文摘Fusion cross sections with weakly bound nuclei have been a subject of great interest in the last few years[1;2]. Inthis field, the basic question is whether complete fusion (CF) is enhanced or suppressed due to diffused density andhigh probability of breakup. The answer to this question depends on the energy regime (above or below Coulombbarrier) and on different target mass regions. Therefore, one important approach to investigate this subject is tostudy the systematic behavior of the CF suppression as a function of the target mass or charge.For fusion induced by 9Be, there are some reported works on the CF on different targets, ranging from 89Y to209Bi[2], but the suppression factor of the CF at near barrier energies does not follow a systematic behavior. Forlighter targets, like 27Al and 64Zn [3;4] and for 238U[5], only total fusion (TF) cross sections were measured. Inorder to contribute to the investigation of the fusion of 9Be, we performed experiments to measure complete andincomplete fusion (ICF) of 9Be on the 187Re and 169Tm targets at energies close to the Coulomb barrier. | Fang Yongde Zhang Ningtao Li Guangshun Liu Minliang Wang Jianguo Guo Song Qiang Yunhua Zhou Xiaohong Zhang Yuhu Lei Xiangguo Zheng Yong Gao Bingshui He Xiaofeng Wang Kailong Ding Bing | 2014 | IMP & HIRFL Annual Report2014,,1: | 0 |

| 6 | Precision interventional radiology显示文摘The recent interest in precision medicine among interventionists has led to the establishment of the concept of precision interventional radiology(PIR).This concept focuses not only on the accuracy of interventional operations using traditional image-guided techniques,but also on the comprehensive evaluation of diseases.The invisible features extracted from CT,MRI,or US improve the accuracy and specificity of diagnosis.The integration of multi-omics and molecule imaging provides more information for interventional operations.The development and application of drugs,embolic materials,and devices broaden the concept of PIR.Integrating medicine and engineering brings new image-guided techniques that increase the efficacy of interventional operations while reducing the complications of interventional treatment.In all,PIR,an important part of precision medicine,emphasizing the whole disease management process,including precision diagnosis,comprehensive evaluation,and interventional therapy,maximizes the benefits of patients with limited damage. | Jiansong Ji Shiji Fang Minjiang chen Liyun zheng Weiqian Chen Zhongwei Zhao Yongde Cheng | 2021 | Journal of Interventional Medicine2021,4,4: | 0 |
| 7 | 首次发现A=130核区中的t-band显示文摘Backbending played a pivotal role in the progress of high-spin structure research[1].This phennomenon was interpreted as a result of band-crossing between two intrinsic configurations which dominate lower-and higher-spin region.Usually the two configurations are differed by two nucleons,which are paired in the former,and unpaired in the latter.According to the strong-coupling scheme,two unpaired quasi-particles can couple to both high-K and low-K configurations in deformed nuclei.Usually only the lower can be identified experimentally since it is favoured by the Gallagher-Moszkowski spin-spin coupling rules[2]. | Guo Song Qiang Yunhua C.M.Petrache Liu Minliang Wang Jianguo A.Astier B.F.Lv D.Bazzacco G.de Angelis Fang Yongde Li Guangshun Zheng Kuankuan Li Ren A.Goasduff K.Hadynska G.Jaworski D.R.Napoli M.Siciliano J.J.Valiente-Dobon | 2018 | IMP & HIRFL Annual Report2018,,1: | 0 |
| 8 | ^(19)Be+^(181)Ta反应系统中^(184)Re同核异能态上下布局比例研究显示文摘Investigation on the fusion dynamics with weakly bound nuclei is important for understanding the element creation in stars and for studying nuclei near the drip lines.Different models have been developed or are under development to explore the fusion mechanisms,ranging from classical to quantum mechanical methods.One of the effective ways to test and develop future realistic models of breakup and fusion is through the investigation of the isomer yield ratios,defined as the cross section of the isomeric states divided by the cross section of the ground states,as they are very sensitive to the angular momentum distribution brought into the fused system. | Li Guangshun Fang Yongde Liu Minliang Zhou Xiaohong | 2018 | IMP & HIRFL Annual Report2018,,1: | 0 |
