摘要

摘要 基于光势模型,研究了在 200 至 1000 MeV 能量范围内质子在 28Si、40Ca、58Ni 和 208Pb 核上散射的计算结果及其与实验数据的比较。这一振幅取决于三个参数,即核子-核子总散射截面、前角散射振幅实部与虚部的比例以及斜率参数。通过对质子-核子散射数据的分析,我们可以确定这些参数,并将它们与自由无界核子质子散射分析中的参数进行比较。

Amplitude of Scattering of Protons on the Bounded Nuclear Nucleons from Analysis of the Proton-Nucleus Scattering

Amplitude of Scattering of Protons on the Bounded Nuclear Nucleons from Analysis of the Proton-Nucleus Scattering

Abstract

The results of calculations and their comparison with experimental data of proton scattering on 28Si, 40Ca, 58Ni and 208Pb nuclei at energies from 200 to 1000 MeV are investigated based on the optical potential model in which the amplitude of scattering of an incident proton on a bound nuclear nucleon is explicitly revealed. This amplitude depends on three parameters, namely, the total nucleon-nucleon scattering cross section, the ration of real to imaginary parts of scattering amplitude at forward angles, and on the slope parameter. This analysis of proton-nucleus scattering data allows one to establish these parameters and compare them with those from the analysis of proton scattering on a free unbounded nucleon.

期刊介绍: The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
