Abstract / Description:Electron-ion momentum spectroscopy is used to investigate the correlated electronic and nuclear motion in fragmentation of H- 2 in 4x10(14) W/cm (2) , 25 fs laser pulses at 795 nm. Reaction channel dependent photoelectron spectra indicate that besides the main, stepwise H-2 ionization H-2(+) dissociation mechanism resulting in the products H(1s)+ H++e(-) a second new mechanism has to be assumed. The momentum distribution of H+ ions in the dissociation channels H(1s)+ H++e(-) and 2H(+)+2e (-) is found to be independent of the kinetic energy of the photoelectrons.
