NEUTRON DECAY OF DEEP-HOLE STATES POPULATED BY THE PB-208(HE-3,ALPHA)PB-207 REACTION AT 102-MEV

Neutron decay of excited hole states populated by the Pb-208(He-3,alpha) reaction at an energy of 102 MeV has been investigated. The alpha-particles were analysed in a magnetic spectrograph positioned at 1.4 degrees and detected with a multi-wire drift chamber. Excitation energies in Pb-207 up to 25 MeV were studied. An array of neutron detectors was positioned around the target at angles ranging from 68 degrees to 209 degrees. The neutron data were analysed in terms of decay into final states, using statistical-model calculations as a tool to extract non-statistical decay
