"In this\r\nthesis, the results of the strong-field photoionization of various gas targets, particularly\r\nof methane are presented. The photoionization was performed by focusing an ultrashort\r\ntwo-color laser pulse into the supersonic gas jet of a Reaction Microscope. The capability\r\nof the Reaction Microscope of simultaneous detection and identification of all charged\r\nionization products enables the channel- and fragment-specific analysis of the ionization\r\nprocess. The tunable relative phase between both components of the two-color field is\r\nan additional control parameter for the experiment. The discrepancy in the yield of lowenergy\r\nphotoelectrons for methane ionization channels with a coincident molecular ion\r\non the one hand and a coincident atomic ion on the other hand resembles similar results\r\nfrom experiments in molecular hydrogen, which could be explained by autoionization\r\nand simultaneous vibrational relaxation of a molecular Rydberg state. Despite the lack of\r\nreference data for Rydberg states of methane with excitations higher than n = 6, it was\r\npossible to estimate their energies and for one ionization channel, it could be demonstrated\r\nthat electrons released by autoionization of Rydberg states between n = 9 and n = 12 are\r\nthe origin of the enhanced low-energy electron yield."^^ .
