The proton and the electron momentum spectra and the proton-proton, el
ectron-electron, and proton-electron ejection correlation spectra indu
ced by 70-ps 532-nm radiation focused to 2 x 10(14) W/cm(2) are measur
ed with a 4 pi electron-ion image spectrometer. The correlation coeffi
cients at this intensity are consistent with (i) sequential fragmentat
ion of H-2 into protons and electrons and (ii) dissociation of H-2(+).
(Ionization of H-2(+) could not be discerned.) The usefulness of the
image spectrometer for probing a variety of problems is discussed. (C)
