Multiply charged negative ions of hydrogen in linearly polarized laser fields
Autor: H. G. Muller, E.J. van Duijn
Publikováno v: Physical Review A. 56:2192-2204
Motivated by the prediction of the appearance of atomic multiply charged negative ions (AMCNI) of hydrogen, induced by a linearly polarized laser field, we present an analytical quantum mechanical treatment of the appearance and structure of AMCNI in
