摘要
一、引言核化学通过观察核素的放射性来研究原子核反应和原子核结构,它是放射化学与原子核物理相互渗透的一门交叉学科。早期核化学研究完全依赖于核反应产物的放射化学分离,接着测量它们的放射性。高分辨γ谱仪的出现,使人们有可能不经过化学分离,直接通过γ能谱测量和分析,就可以在同一样品中鉴定一百多个放射性核素。另一方面,随着核科学研究的发展,希望一次实验能得到尽可能多的核反应讯息。
Measurement of γ-ray spectra and method of data analysis are descri-bed for the research of nuclear chemistry. Gamma-ray spectra are collected as afunction of time and are analysed by the computer codes GAMA33 or LEONE.Decay curves are constructed by selection of characteristic γ-rays using the com-puter code SORT. The analysis of half-life and identification of nuclides areperformed with the interactive computer code TAU85 and Tektronix graphics ter-minal. Nuclear reaction cross-sections are calculated on weighted average of all theobserved γ-rays for each nuclide after duplicate or erroneous identifications are screened.
