Angular resolved photoelectron spectra of H₂ in strong fields — •Timo Wilbois and Hanspeter Helm — Department of Molecular and Optical Physics, Stefan-Meier-Str. 19, 79104 Freiburg, Germany

We measured angular resolved photoelectron spectra and total ionisation rates of molecular hydrogen in strong laser fields at several wavelengths. Short pulses in the fs regime were used to ionise a thermal sample of H₂ in an imaging spectrometer. Electrons are detected by multichannel plates followed by a phosphor screen, which is photographed by a CCD camera. The angular resolved momentum distribution of the photoelectrons is retrieved by use of a backinversion algorithm [1].
In this work experimental results are presented, which can be used for comparison with available theoretical approaches [2,3].
