Resumen:
An improved Weisskopf-Wigner approximation allows to obtain a closed form for the survival amplitudeand the ionization amplitudes of atoms subject to laser pulses. The improvement avoids the numerical solution ofa Volterra integro-differential equation obtained by modeling full initial state coupling to the continuum as wellas 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.
