bibo_abstract:
- In this paper a generalized Fourier transform method for solving the initial-value
problem associated with the interaction of an atom with a semiclassical laser
field is presented. The method is combined with a variational technique of expanding
the atomic potential. The energy-transform of the total wavefunction is obtained
algebraically, while the wavefunction itself, at a time t, is given as a quadrature
over the explicit algebraic expressions. Furthermore, the method permits one
to determine the long-time limit t --> + infinity without the quadrature. Analytic
expressions of the ATI transition amplitudes are given. As an illustration of
the use of the method, we apply it to the problem of determining the above-threshold-detachment
(ATD) spectra of a 3D model of H-. Results of computations for (a) the stationary
ATD spectra, (b) the perturbed energies of the initial bound state, (c) the total
rate of detachment and (d) the ATD spectra for individual photon absorption channels
are presented for a range of intensities.@eng
