Abstract
The Weakest Bound Electron Potential Model (WBEPM) is used to calculate tra nsition probabilities between LS multiplets of Be I, Be II, Mg I, and Mg II . In this calculation, a coupled set of equations is employed to determine effective charges Z* and effective quantum numbers n* and l* using, as inpu t data, experimental energy levels and radial expectation values obtained w ith the numerical Coulomb approximation. Transition probabilities between h ighly excited states are evaluated using modified hydrogenic wavefunctions. Good agreement is seen in comparisons of the present results with those fr om other works. (C) 2001 Academic Press.
