Exact PWBA virtual photon spectrum for A(γv, D)R

Title of program: VPSPEC Catalogue Id: AAOQ_v1_0 Nature of problem Quite often in nuclear and intermediate energy physics it is desirable to extract photon induced cross sections from measured electron induced cross sections. Assuming the validity of virtual photon theory this extraction can be carried out by means of a virtual photon spectrum. Versions of this program held in the CPC repository in Mendeley Data AAOQ_v1_0; VPSPEC; 10.1016/0010-4655(83)90043-7 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)程序名称：VPSPEC 目录编号：AAOQ_v1_0 待解决问题 在核物理与中能物理领域，研究者常需从实测电子诱发反应截面中提取光子诱发反应截面。若虚拟光子理论（virtual photon theory）成立，则可通过虚拟光子谱完成该提取工作。 存放在Mendeley Data的CPC程序库中的本程序版本： AAOQ_v1_0; VPSPEC; 10.1016/0010-4655(83)90043-7 本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2019）
