Improved Weisskopf-Wigner approximation for atomic ionization by short laser pulses

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 coupl...

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.
