Absolute cross sections of compound nucleus reactions

Abstract
The program SEEF is a Fortran IV computer code for the extraction of absolute cross sections of compound nucleus reactions. When the evaporation residue is fed by its parents, only cumulative cross sections will be obtained from off-line gamma ray measurements. But, if one has the parent excitation function (experimental or calculated), this code will make it possible to determine absolute cross sections of any exit channel.

Title of program: SEEF
Catalogue Id: ACPJ_v1_0

Nature of problem
One of the experimental methods used to determine cross sections of compound nucleus reactions is based on gamma rays measurements. These rays are emitted during the radioactive decay of evaporation residues. Nevertheless, when the compound nucleus evaporates charged particles, the result evaporation residue is fed by his parents during and after irradiation. So, one cannot talk of absolute cross sections in these cases.

摘要
程序SEEF是一款采用Fortran IV语言编写的计算机代码，用于提取复合核反应（compound nucleus reactions）的绝对截面（cross sections）。当蒸发残核（evaporation residue）由其母核馈入时，通过离线γ射线测量仅能获得累积截面。但若已知母核的激发函数（excitation function，可为实验测量或理论计算所得），则借助本代码即可确定任意反应道（exit channel）的绝对截面。

程序名称：SEEF
目录编号：ACPJ_v1_0

问题本质
用于测定复合核反应截面的实验方法之一基于γ射线测量。此类射线产生于蒸发残核的放射性衰变过程。然而，当复合核蒸发带电粒子时，所生成的蒸发残核会在辐照期间及辐照后由其母核馈入，因此在此类场景下无法得到绝对截面。
