LETTER TO THE EDITOR

The stabilization dynamics of model He beyond the dipole approximation and with two active electrons is investigated in the presence of a high-intensity and high-frequency laser pulse. We show that the magnetic-field component of the laser pulse and the electron–electron interaction jointly suppress the dichotomy of the wavefunctions as well as the atomic stabilization.
