Advances in Atomic Structure Calculations

February 19, 2017
Author(s)
Charlotte F. Fischer
Correlation and relativistic effects are both needed for accurate atomic structure calculations of energy levels and their atomic properties. For transition probabilities between low-lying levels of a spectrum, accurate wave functions for the outer region

Relativistic CI calculations of spectroscopic data for the 2p6 and 2p53l configurationsin Ne-like ions between Mg III and Kr XXVII

P. Jonsson, P. Bengtsson, J. Ekman, S. Gustafsson, L. B. Karlsson, G. Gaigalas, D. Kato, Charlotte F. Fischer, I. Murakami, H. A. Sakaue, H. Hara, T. Watanabe, N. Nakamura, N. Yamamoto
Energies, E1, M1, E2, M2 transition rates, oscillator strengths, and lifetimes from relativistic configuration interaction calculations are reported for the states of the 2p6, 2p53s, 2p53p, and 2p53d, configurations in all Ne-like ions between Mg III and

New Version: Grasp2K Relativistic Atomic Structure Package

February 19, 2013
Author(s)
P. Jonsson, G. Gaigalas, J Bieron, Charlotte F. Fischer, I. P. Grant
A revised version of Grasp2K [P. Jonsson, X. He, C. Froese Fischer, and I.P. Grant, Comput. Phys. Commun. 177 (2007) 597] is presented. It supports earlier non-block and block versions of codes as well as a new block version in which the njgraf library

Correlation effects on transition probabilities in Mo vi

June 13, 2012
Author(s)
Charlotte F. Fischer
The effect of correlation on transitions in Mo vi from 4p64d 2D and 4p65s 2S to 4p64f, 4p65p, 4p65f, 4p54d2 with J = 1/2 - 7/2 is investigated. Non-relativistic correlation studies show the near degeneracy of 4p54d2(3F) 2Fo and 4p54d2(1G) 2Fo configuration
