摘要: 用C语言编写成γ-电子级联过程的蒙特卡罗模拟程序,可在IBM系列微机上运行。程序可实时显示粒子输运与反应的模拟物理过程,并可有选择地累积各种谱。结果以事件方式与谱方式记录,可进行数据再处理。目前适用γ能区为0.1~500MeV,可扩展至其他能区。程序可用于γ探测器研制、核辐射防护和核医学等领域。

Abstract: A Monte Carlo code writen by C language for simulating the gamma-electron shower in material bas been realized on microcomputer. The programme can actively display the physical process of particle transport and reaction, and can accumulate various spectra selected by the user. The results are stored event by event on the disk and can be retreated afterward. The energy region available is 0.1 to 500MeV, but can easily be extended to lower or higher energies. The code could be used in the area such as gamma detection, protection of nuclear radiation and nuclear medicine.

Key words: C language, Monte Carlo simulation, gamma-electron shower
