  • The scattering of positronium by lithium 
    Ray, H (Institute of Physics, 2000-10)
    The scattering of positronium (Ps) by lithium (Li) is investigated using the static-exchange approximation and a two-state close-coupling approximation (CCA) including exchange. The major effect of very high polarizability ...
  • 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 ...
  • Studies on the E2-transition in CoXVII 
    Ray, H (EDP Sciences, 2002-09)
    The spectrum of the solar corona, plasma spectra, astrophysical objects and fusion devices exhibit forbidden lines in alkali-like ions. Ions belonging to the iron group are particularly important in this respect. More ...
  • Term values of Na-like iron group highly stripped ions using coupled-cluster theory 
    Ray, H (Institute of Physics, 2002-07)
    More accurate term values, a few line strengths and transition probabilities for the E2 transitions of the iron group highly stripped ions Fe XVI, Co XVII and Ni XVIII are reported. We have used the fully relativistic ...
