Description
Radiative decay rates are computed with the atomic structure code superstructure for the 2s2p^3^ ^5^S^o^_2_ - 2s^2^2p^2^ ^3^P_1_, ^3^P_2_ and ^1^D_2_ 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 ^5^S^o^_2_ radiative lifetime and the B=A(^5^S^o^_2_-^3^P_2_)/A(^5^S^o^_2_-^3^P_1_) 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 ^1^D_2_ are not expected to be accurate to more than 20%. ***************************************************************************** * * * The author(s) did not provide their tables as announced in the paper. * * Only some of the published tables are here. * * * *****************************************************************************
