Suppression of electron correlation and of autoionization by strong laser fields

General considerations and explicit computations using highly correlated Hylleraas-type wavefunctions demonstrate how doubly electronically excited autoionizing helium can be stabilized in the presence of a KrF laser at laboratory field intensities. This type of stabilization is due to the abrupt suppression of the dynamical electronic correlation as the field intensity is increased beyond a critical value. The generality of the result is stressed.
