Energies and transition wavelengths for Li II, Be III, B IV, C V embedded in Debye plasmas

We have carried out non-relativistic calculations to investigate the effect of Debye plasmas screening on the doubly excited nonautoionizing P-1,3(e) and D-1,3(o) states of Li II, Be III, B IV, and C V using highly correlated exponential wave functions within the framework of Ritz variational principle. The 2p(2) P-3(e), 2p3p P-1(e), and 2p3d D-1,3(o) states energies, and wavelengths for the 2p3p P-1(e) -> 2p3d D-1(o), 2p(2) P-3(e) -> 2p3d D-3(o), 2p3p P-3(e) -> 2p3d D-3(o), and 2p3p P-3(e) -> 2p3d D-3(o) transitions for different Debye lengths are reported. Comparisons are made with the existing results. Results for B IV and C V for different screening parameters are reported for the first time in the literature. Transition wavelengths show interesting behavior with increasing screening parameters and nuclear charge. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3692085]
