Abstract:
Radiative decay rates are computed with the atomic structure code
superstructure for the 2s2p3 5So2 - 2s22p2 3P1,
3P2 and 1D2 intercombination transitions of the carbon
isoelectronic sequence (6≤Z≤28). Contributions from configuration
interaction and relativistic corrections are carefully
studied, in particular the spin-spin interaction that is shown to be
of considerable importance for low Z. By extensive comparisons with
other theoretical datasets and measurements of the 5So2
radiative lifetime and the
B=A(5So2-3P2)/A(5So2-3P1) branching ratio, we are
able to assign accuracy ratings to the present transition
probabilities. The transitions to the ground term are believed to be
accurate to better than 10% whereas the smaller A-values belonging to
transitions to the 1D2 are not expected to be accurate to more
than 20%.
