裂变位垒参数是表征原子核裂变不稳定性的最基本的参数,它包括位垒垒高V和位垒曲率hω。在很多情况下又有双峰位垒,应包括内垒的垒高V1和曲率hω1及外垒的垒高V2和曲率hω2。这里需指出,除了垒高和曲率外,还应包括裂变能级密度,而且两者有很强的依赖性。在涉及到裂变截面的核反应模型计算和核数据评价中,裂变位垒参数及裂变能级密度参数是非常关键的输入模型参数。 编篡的裂变位垒参数数据文档“FBP.DAT”是为核反应模型计算和核数据评价模型计算输入用的“中国评价核参数库（CENPL）”的一个子库。目前,更新的裂变位垒参数数据文档 The fission barrier parameter is the most basic parameter for characterizing the fission instability of the nucleus. It includes the basement base height V and the barrier curvature hω. In many cases there are bimodal barriers, should include the basement of the basement height V1 and curvature hω1 and the outer basement height V2 and curvature hω2. It should be noted here that in addition to the base height and curvature, fission level densities should also be included, and both have strong dependencies. Fission barrier parameters and fission level density parameters are very important input model parameters in nuclear reaction model calculation and nuclear data evaluation involving fission cross section. The codified fission barrier parameter data document “FBP.DAT” is a sub-library of the “China Evaluation Nuclear Parameter Library (CENPL)” used for calculation of nuclear reaction model calculation and nuclear data evaluation model. Currently, updated fission barrier parameter data files
