# A program for computing autoionization properties

## Description

Abstract A program for computing atomic autoionization widths, decay rates and lifetimes is presented as a new part of the MCHF atomic structure package. The method used is based on the “configuration interaction in the continuum” theory by Fano, in which the continuum is computed independently of the discrete part and the width is given by the “Golden Rule” formula. The program allows for correlation in the discrete part of the atomic state function and in the target, through multiconfiguration expan... Title of program: MCHF_AUTO Catalogue Id: ACLD_v1_0 Nature of problem This program is an extension of the MCHF atomic structure package to calculations of autoionization rates and line widths. Versions of this program held in the CPC repository in Mendeley Data ACLD_v1_0; MCHF_AUTO; 10.1016/0010-4655(93)90021-4 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
