NLOM — a program for nonlocal optical model calculations

Abstract A FORTRAN program NLOM for nonlocal optical model calculations is described. It is based on a method recently developed by Kim and Udagawa, which utilizes the Lanczos technique for solving integral equations derived from the nonlocal Schrödinger equation. Title of program: NLOM Catalogue Id: ACHU_v1_0 Nature of problem It calculates the elastic scattering cross sections of a projectile (either a nucleus or a nucleon) with spin, 0 or 1/2 scattered by a non- local potential on the basis of the optical model. Versions of this program held in the CPC repository in Mendeley Data ACHU_v1_0; NLOM; 10.1016/0010-4655(92)90080-I This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要 本文介绍一款用于非定域光学模型（Optical Model）计算的Fortran（FORTRAN）程序NLOM。该程序基于Kim与Udagawa近期提出的方法，借助兰乔斯（Lanczos）技术求解由非定域薛定谔（Schrödinger）方程推导得到的积分方程。 程序名称：NLOM 目录编号：ACHU_v1_0 问题特性 本程序基于光学模型（Optical Model），计算自旋（spin）为0或1/2的入射粒子（projectile，可为原子核（nucleus）或核子（nucleon））经非定域势（non-local potential）散射后的弹性散射截面（elastic scattering cross sections）。 Mendeley数据中CPC库存储的该程序版本 ACHU_v1_0; NLOM; 10.1016/0010-4655(92)90080-I 本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2019年）
