An equivalent energy-dependent local potential corresponding to Coulomb plus Graz separable potential is constructed through simple rearrangement of the Schrödinger equation. It is conjectured that local Coulomb-like potential is equally applicable for the traditional phase function method. The merit of our constructed potential is thus judged by studying nucleon–nucleon and alpha–nucleon systems through the phase function method. Good agreement in phase shift values with standard data is achieved.

相等效库仑势

通过简单地重新排列薛定谔方程，构建了一个等效的与能量相关的局部势，对应于库仑加格拉茨可分离势。据推测，局部类库仑势同样适用于传统的相函数方法。因此，通过相函数法研究核子-核子和α-核子系统，可以判断我们构建的势能的优劣。实现了与标准数据的相移值的良好一致性。
