The calculation of multiphoton ionization rates of the hydrogen molecular ion

Abstract We present the Floquet method of calculation of multiphoton ionization rates from the dressed σ^+ _gand σ^+ _ustates of H^+ _2 . Our software allows a determination of ionization rates for a range of laser frequencies, intensities and internuclear separations. The theoretical method is discussed and instructions for use of the accompanying computer program, which also produces ionization rates for DC field ionization, are given. Title of program: h2pacflo, h2pinit Catalogue Id: ADIZ_v1_0 Nature of problem Multiphoton ionization of H2+ in intense (up to 10^14W cm^-2) laser fields over a range of internuclear distances and laser frequencies; DC field ionization of H2+ for comparable (and higher) field strengths.
