Secondary peaks in the atomic ionization by a resonant laser pulse

The above-threshold ionization of atoms by XUV short laser pulses with frequencies resonant with a ground-excited state transition is investigated. A theory based on a variational expression with trial wave functions for the final and the initial states is presented. For the former we use a Coulomb-...

A theory based on a variational expression with trial wave functions for the final and the initial states is presented. For the former we use a Coulomb-Volkov wave function, and for the latter a close-coupling solution of the time-dependent Schrödinger equation considering a few bound states and their depletion towards the continuum. We find that this discrete-continuum Coulomb-Volkov theory provides a very good description of the photoelectron spectrum. In particular it accounts for the splitting of the above-threshold ionization peaks by Rabi oscillations and the appearance of secondary-peaks observed in full numerical simulations. 2012 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_17426588_v397_n1_p_Bustamante http://hdl.handle.net/20.500.12110/paper_17426588_v397_n1_p_Bustamante
