cited By 39International audienceIn the calculation of the dynamic polarizability including electronic correlation and ensuring gauge invariance, contributions of spectroscopic states and quasispectral series are analyzed. An improvement of our original electric-field variant ket approach is proposed and illustrated by application to H and LiH systems. © 1992 The American Physical Society
