QEDMOD: Fortran program for calculating the model Lamb-shift operator
Description
Abstract We present Fortran package QEDMOD for computing the model QED operator ^(hQED)that can be used to account for the Lamb shift in accurate atomic-structure calculations. The package routines calculate the matrix elements of ^(hQED)with the user-specified one-electron wave functions. The operator can be used to calculate Lamb shift in many-electron atomic systems with a typical accuracy of few percent, either by evaluating the matrix element of ^(hQED)with the many-electron wave functio...
