本文提出了一种计算核电子跃迁激发的量子力学方法。重点是对电多次波和磁偶极子NEET跃迁矩阵元的显式计算和选择规则的讨论。这种形式主义的一个特点是，与核伙伴有关的矩阵元部分与核部分辐射宽度有关，这是一个可测量的量。这使得它可以更可靠地评估NEET概率。沿着给出了{sup 189}Os、{sup 197}Au和{sup 237}Np中NEET概率的预测结果以及可用的测量数据。
A quantum-mechanical formalism to calculate the nuclear excitation by electron transition (NEET) is presented. Emphasis is on the explicit calculations of the transition matrix elements for electric multiple and magnetic dipole NEET and discussions of the selection rules. One of the features of this formalism is that the part of the matrix element in connection with the nuclear partner is related to the nuclear partial radiative width, which is a measurable quantity. This makes it available to evaluate the NEET probability more reliably. The predicted results for NEET probabilities in {sup 189}Os, {sup 197}Au, and {sup 237}Np are given along with the available measured data.
