【摘要】通过分析和计算锕系核裂变截面和全套中子反应截面获取了一组锕系核的裂变位垒参数.Fm)在此基础上,广泛收集实验裂变位垒参数,通过比对和评价,推荐了本组的129个核素(109Cd—255的实验裂变位垒参数.此外,对收集的不同裂变位垒参数作了分析与评价,推荐了7组实验和1组模型计算的裂变位垒参数,并组建了中国评价核参数库裂变位垒参数子库(CENPL FBPL).更多还原

【Abstract】 The fission barrier parameters for actinide nuclei were obtained by analysis and calculations of fission cross-sections and complete neutron reaction cross sections. A lot of experimental fission barrier parameters from different authors were collected. A set of fission barrier parameters for 129 nuclei ranging from¹⁰⁹Cd to²⁵⁵Fm were recommended after performing comparisons, evaluations and systematics extrapolations for these extracted fission barrier parameters in model calculations of fission cross-sections and collected fission data. In additions, a fission barrier parameter library, Chinese Evaluated Nuclear Parameter （Library-）Fission Barrier Parameter Library（CENPL-FBPL）, was constructed, which consists of seven sets of experimental fission barrier parameters and a set of ones from model calculations.更多还原
