摘要：

We present calculations of autoionization widths using a fully numerical multiconfigurational Hartree-Fock method (MCHF). Energy positions and autoionization rates are given for several doubly-excited states lying below the n = 2 threshold in He I and H-. Particular attention is given to orthogonality considerations in the computation of the autoionization widths. The method is extended to the 1s2p2 2D, 1s2s(3S)3d 2D and 1s2s(3S)4d 2D states of Li I. To the authors' knowledge, our MCHF value, 12.5 meV, is the first result obtained for the autoionization width of the 1s2s(3S)4d 2D state. Comparison is made with other theoretical results and with experimental values and we point out several inconsistencies between the two sets of results.
