Relativistic and second order Z-dependent calculations for the 1s-2p transitions in Li I-like ions

The transition arrays 1s 2 2s-1s2s2p and 1s 2 2p-1s2p 2 in Li-like ions are calculated by means of relativistic Z-expansion combined with second order calculations of the electron electrostatic interaction. The results of the ab initio calculations for 6
