Abstract
Double-quantum ionization for Rydberg hydrogen is studied. The variation of ionization rates with wavelength is shown for linearly polarized (LP) and circularly polarized (CP) radiations. For performing the infinite summations over the intermediate states, pseudostate summation technique (PST) is used which is fast and efficient. Presently, the numerical values of two-quantum and three-quantum ionization rates from ground state and metastable 2s state only are available in the literature. The present work reports the calculations for the double-quantum ionization rates from higher excited levels of hydrogen. Numerical data is also presented for comparison with future experiments.
