Accurate Calculations of Interstellar Lines of Mg+ Using the Coupled Cluster Approach

Majumder, S; Merlitz, H; Gopakumar, G; Das, B. P; Mahapatra, U. S; Mukherjee, Debashis (The American Astronomical Society., 2002-07)

One of the most successful ab initio, highly correlated all-order many-body methods, the relativistic coupled cluster theory, is employed to calculate excitation energies of the doublet states of Mg+ and allowed transitions ...
Density dependence of solar emission lines of oxygen-like ions

Raju, P. K; Dwivedi, B. N (D.Reideal Publishing Co.,, 1978-12)

Assuming steady state conditions, the occupation of 9 levels of oxygen-like ions: Ne iii, Mg v, Si vii, S ix, and Ar xi have been computed as a function of electron density and temperature. The following physical processes ...
Studies on E2 Transition in the Na-like Highly Stripped Ion Fe XVI

Ray, H (The American Astronomical Society, 2002-11)

The spectrum of the solar corona and plasma spectra in astrophysical objects and fusion devices exhibit forbidden lines in alkali-like ions. Ions belonging to the iron group are particularly important in this respect. The ...
