摘要
给出了一个计算核反应总截面的参数化公式.用此公式计算了包括低能、中高能区大量系统的核反应总截面,且和实验数据进行了比较.讨论了反应总截面σ_R与中子过剩自由度(N-Z)的关系,以及相互作用半径R与轰击能量E_(cm)^-((1/3))的关系.
A unified parametrized formula of total reaction cross section σR from low energy to intermediate and high energy has been proposed. Most of the experiment results in whole energy range can be reproduced by this parametrization. The relation of σR with neutron excess degree of freedom (N-Z) and the relation of interaction radius R with incident energy E_(cm)～(-1/3) have also been discussed.
