We investigate the fragmentation of the triatomic hydrogen molecule H3 in a triple-coincidence experiment. A singl e rovibronic state of H3 is laser prepared and its breakup into three hydrogen atoms H(1s) is monitored by time- and positi on-sensitive multihit detectors. For each triple hit, the momentum vectors of the three H(1s) fragments are determined. The sixfold differentia l 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 H3 initial electronic state. ©1999 The American Physical Society
