Abstract
A Z-expansion method is used to calculate the energies (including first-order relativistic corrections) and probabilities of 1s22s2S1/2-1s2s2p4P5/2 and 1s22s2 1S0-1s22s2p3P2 magnetic quadrupole transitions in the lithium and beryllium sequences respectively. It is found that, compared to spin-spin autoionization to the 1s2kf2F5/2 continuum level, the magnetic quadrupole decay of 1s2s2p4P5/2 to the ground state becomes increasingly significant as the nuclear charge increases. Probabilities for the 1S0-3P2 transition are found to be small.
