摘要: 本文分析了应用直接作用模型计算中子非弹性散射截面时应当如何调整参数。由于积分截面和角分布都与核子间相互作用位的位阱深度V0的平方成正比,因此它就是影响计算结果的主要参数。本文给出了只调整其它参数,然后自然确定V0的目的。实践证明这种目的可以大幅度地减少计算机的计算量。

Abstract: The process of adjusting parameters which is oppeared in the direct interaction model of inelastic neutron scattering is investigated.Since the integral cross section and angular distributions are both proprotional to the square of V0 which is the potential well depth of interaction potential between nucleons,V0 influences the calculated resulth most effectively.A process is given in this paper by which V0 can be determined naturally after other parameters having been adjusted.By using this process the computer work is greatly reduced.
