Abstract:
An improved Weisskopf-Wigner approximation allows to obtain a closed form for the survival amplitude and the ionization amplitudes of atoms subject to laser pulses. The improvement avoids the numerical solution of a Volterra integro-differential equation obtained by modeling full initial state coupling to the continuum as well as transitions between initial state and other discrete states. The calculations are made in the velocity gauge. The improved approximation compares well with a full TDSE numerical solution for Hydrogen. © Published under licence by IOP Publishing Ltd.
