Abstract

By numerically solving the time-dependant Kohn-Sham equation with initial states obtained through self-consistent density-functional theory, we studied, in a numerical way, photoionization of a one-dimensional helium cluster model exposed to intense laser pulses. Enhanced ionization effect, which is similar to the CREI effect for small molecules, was observed and the associated mechanism was discussed. Our numerical results present good agreement with previous conclusions using different algorithms.
