New Version: Grasp2K Relativistic Atomic Structure Package
Per Jönsson,Gediminas Gaigalas,Jacek Bieron,C. Froese Fischer,C. Froese Fischer,Ian P. Grant +5 more
TL;DR: A revised version of Grasp 2 K supports earlier non-block and block versions of codes as well as a new block version in which the njgraf library module has been replaced by the librang angular package developed by Gaigalas based on the theory of Dirac–Hartree–Fock.
Journal ArticleDOI
GRASP2018-A Fortran 95 version of the General Relativistic Atomic Structure Package
TL;DR: An updated Fortran 95 version of the recommended block versions of programs from Grasp 2K Version 1_1 for large-scale calculations Jonsson et al. (2013).
Journal ArticleDOI
Advanced multiconfiguration methods for complex atoms : I. Energies and wave functions
TL;DR: In this paper, a review of variational MCHF and Dirac-Hartree-Fock (MCDHF) is presented, where the multireference single and double process for generating expansions and the systematic procedure for monitoring convergence are discussed.
Journal ArticleDOI
An MCHF atomic-structure package for large-scale calculations
TL;DR: The MCHF program has been modified to include optimization on an energy functional that is a weighted average of energy functionals for expansions of wavefunctions for different LS terms or parity, thus facilitating Breit–Pauli calculations for complex atomic systems and for computing targets in collision calculations.
