摘要:

利用自洽相对论平均场模型的静电荷密度分布,采用相对论分波展开方法研究了电子或正电子与$^{208}$ Pb、$^{12}$ C、$^{12,16}$ O和$^{28, 32}$ S的弹性散射截面,并计算了$^{12, 16}$ O和$^{28, 32}$ S的电荷形状因子.数值结果与现有数据进行了比较。计算表明,$^{12}$ O和$^{28}$ S的扩展电荷密度分布对电子或正电子散射的截面以及电荷形状因子有明显的影响.

英文摘要:

We investigate the cross sections of the elastic electron or positron scattering from $^{208}$Pb, $^{12}$C, $^{12,16}$O and $^{28, 32}$S 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 for $^{12, 16}$O and $^{28, 32}$S. The numerical results are compared with the available data. Calculations indicate that the extended charge density distributions of $^{12}$O and $^{28}$S have observable effects on the cross sections of the electron or positron scattering as well as the charge form factors.
