Abstract

On the bais of two programs, calculations are carried out for energies, probabilities of radiative transitions and nonradiative decays, and lifetimes of levels of two-electron systems 2l.4l′. The results of the two calculations are compared for a wide range of Z. Possible channels of radiative transitions and nonradiative decays are discussed. Their relative contribution to the total probability is evaluated. This evaluation is compared with data obtained by calculations, on the basis of which a conclusion is made about the contribution of correlation and relativistic effects. The Z-dependences are investigated for each of the parameters under consideration. A comparison is made with the results of other calculations.
