Abstract

In the framework of the Rarita–Schwinger formalism, a description is given of the wave functions, as well as the matrix elements of the electromagnetic and weak neutral currents of the nuclei of half-integer spin. Multipole decompositions of the matrix elements of these currents are constructed in the Breit reference frame. In the approximation of the effective electroweak current of the nucleus, the corresponding differential scattering cross sections of longitudinally polarized leptons are obtained.

半整数自旋核对极化轻子的相干弹性散射

摘要

在Rarita-Schwinger形式主义的框架中，对波函数以及半整数自旋核的电磁和弱中性电流的矩阵元素进行了描述。这些电流的矩阵元素的多极分解是在Breit参考系中构建的。在近似原子核的有效电弱电流的情况下，获得了纵向极化的轻子的相应微分散射截面。
