Relativistic and Radiative Effects in He-like Ions

Ionization potentials of 2 3PJ, 2 1P1, 2 3S1, 2 1S0 states are calculated. Relativistic and radiative effects are taken into account. Non-relativistic energies are calculated in the framework of the Z-expansion perturbation theory. Results for ionization potentials and wavelengths of transitions 1 1S0-2 1P1, 1 1S0-2 3P1, 1 1S0-2 3P2, 1 1S0-2 3S1 are given for ions with Z = 10-42.
