摘要

在变形核的弹性电子散射（DWBA）中，采用了电荷密度，分别反映了目标核的长圆形和扁圆形。在第一个衍射截面最小值附近的散射角处，发现了差分截面和电子自旋不对称与形状有关的明显证据。以碰撞能量在 150 到 500 MeV 之间的 \(^{27}\)Al 核的结果为例。

On the influence of nuclear deformation in the elastic scattering of polarized electrons

Elastic electron scattering from deformed nuclei is described within the distorted-wave Born approximation (DWBA) by employing charge densities which reflect, respectively, the prolate and oblate shapes of the target nucleus. Clear evidence for the shape dependence of the differential cross section and of the electronic spin asymmetry is found at scattering angles in the vicinity of the first diffractive cross section minimum. As an example, results for the \(^{27}\)Al nucleus at collision energies between 150 and 500 MeV are provided.
