OWL: A code for the two-center shell model with spherical Woods-Saxon potentials

A Fortran-90 code for solving the two-center nuclear shell model problem is presented. The model is based on two spherical Woods–Saxon potentials and the potential separable expansion method. It describes the single-particle motion in low-energy nuclear collisions, and is useful for characterizing a broad range of phenomena from fusion to nuclear molecular structures.本文提供了一套用于求解双中心核壳模型问题的Fortran-90代码。该模型基于两个球形Woods-Saxon势（Woods–Saxon potential）以及势可分离展开方法，可描述低能核碰撞中的单粒子运动，且能够用于表征从核熔合到核分子结构等广泛的物理现象。
