从氘核数据中提取中子光吸收总截面

On extraction of the total photoabsorption cross section on the neutron from data on the deuteron

M. I. Levchuk, A. I. L'vov

摘要:

本文提出了一种改进的方法,用于从能量小于1.5GeV的氘核数据中求出中子的总光吸收截面。它包括展开的拖尾效应所造成的费米运动的核子在氘核中,也考虑到非添加剂的贡献,氘核截面由于最终状态的相互作用的粒子在单和双π介子光生。该程序适用于现有数据的分析。

英文摘要:

An improved procedure is suggested for finding the total photoabsorption cross section on the neutron from data on the deuteron at energies < 1.5 GeV. It includes unfolding of smearing effects caused by Fermi motion of nucleons in the deuteron and also takes into account non-additive contributions to the deuteron cross section due to final-state interactions of particles in single and double pion photoproduction. This procedure is applied to analysis of existing data.
