【 摘 要 】

Photoionization of Rydberg atomic state by the ultra-short wavelet pulses (USWP) is calculated in the frame of perturbation theory with the use of Kramers ionization cross-section. Two simplest types of USWP are considered, namely, cosine and sine pulses. Analytical expressions containing scaling functions for photoionization probability are derived for above- mentioned USWP.
