Abstract

A nuclear photographic emulsion method was used to study the charge-state, ionization, and angular characteristics of secondaries produced in inelastic interactions of 56Fe nuclei at 1.8 GeV/nucleon with H, CNO, and AgBr nuclei. The data obtained are compared with the results of calculations made in terms of the Dubna version of the cascade evaporation model (DCM). The DCM has been shown to satisfactorily describe most of the interaction characteristics for two nuclei in the studied reactions. At the same time, quantitative differences are observed in some cases.

摘要

采用核照相乳胶法研究了56Fe核在1.8 GeV/核子能量下与H、CNO和AgBr核发生非弹性相互作用时产生的次级粒子的电荷态、电离和角特性。将获得的数据与根据级联蒸发模型（DCM）的杜布纳版本所做的计算结果进行了比较。结果表明，DCM能够令人满意地描述所研究反应中两个原子核的大多数相互作用特性。同时，在某些情况下也观察到了定量差异。
