摘要
We investigate the fragmentation of the triatomic hydrogen molecule H(3) in a triple-coincidence experiment. A single rovibronic state of H(3) is laser prepared and its breakup into three hydrogen atoms H(1s) is monitored by time- and position-sensitive multihit detectors. For each triple hit, the momentum vectors of the three H(1s) fragments are determined. The sixfold differential cross section of the fragment momentum components in the center-of-mass frame is found to be highly structured and to depend sensitively on the H(3) initial electronic state.
