电子与奇异丰质子核弹性散射的微分截面和电荷形状因子

Differential cross sections and charge form factors of elastic electron scattering from exotic proton-rich nuclei

用相对论分波展开法研究了电子与12,16O和28,32S弹性散射的微分截面以及12,16O和28,32S的电荷形状因子,其中核的电荷密度分布利用自洽相对论平均场模型来计算。数值结果与已有的实验数据进行了比较,结果表明目前的理论是可靠的,计算显示12O和28S的扩展的电荷分布对于电子-核散射的微分截面以及电荷形状因子具有可观测的效应。

We investigate the differential cross sections of the elastic electron scattering from ^12,16O and ^28,32S by the relativistic partial - wave expansion method using the static charge density distribution from the self- consistent relativistic mean field model and also calculate the charge form factor of ^12,16O and ^28,32S.Zhe numerical results are compared with the available data. The results show that the present theory is reliable. The Calculations indicate that the extended charge density distributions of ^12O and ^28S have observable effects on the cross sections of the electron scattering and the charge form factors.
