用于剂量计算的核反应总截面经验公式

Empirical formula of total cross section of nuclear reaction for dose calculation

在核物理及核物理应用研究中,利用核反应总截面经验公式进行理论计算具有现实意义。这方面的计算公式很多,本文以中能区应用的Kox经验公式为基础,结合重离子治疗肿瘤计算剂量深度模型的需要,对Kox经验公式的参数进行了修正,使其具有更广泛的应用价值,同时对修正参数的物理意义进行了探讨。

Empirical formulas play important role in some theoretical calculations in applied nuclear physics. There are lots of empirical formulas for total cross section of nuclear reaction. In this paper, we use Kox empirical formula as a basis to estimate doses in tumor therapy with heavy ions. We have revised some parameters of Kox empirical formula in order to get more precise values in the application. At the same time, the physical meaning of these revised parameters are discussed.
