Abstract
The authors have calculated oscillation strengths and transition probabilities for transitions between the 1s22s2, 1s22s2p and 1s22p2 states, namely: 1S0e to 1P10; 1P10 to 1D2e; 1P10 to 1S0e and 3PJ0 to 3PJ'e. For allowed transitions, use of elaborate wave-functions is more important than relativistic corrections up to Z approximately=14. For higher Z, relativistic corrections become somewhat more important.
