We introduce the concept of neutron-proton two-particle units (np-Weisskopf units) to be used in the analysis of the (3He,p) and (p,3He) reactions on nuclei along the N=Z line. These are presented for the conditions relevant to the (n,j,) orbits expected from 16O to 100Sn. As is the case of the Weisskopf units for electromagnetic transitions, the np-WU's will provide a simple, yet robust, measure of isoscalar and isovector np pairing collective effects.

中子-质子对转移反应和相应的 Weisskopf 型单元

我们介绍的中子-质子两粒子单元的概念(NP -Weisskopf单位)在(分析中使用3赫,p)和(p,3He) 核上沿 N=Z 线的反应。这些是针对相关条件提出的(n,j,) 轨道预计从16 O 到100 Sn。与用于电磁跃迁的 Weisskopf 单元的情况一样,np -WU 将提供一种简单而稳健的等标量和等向量np配对集体效应的度量。
