NEUTRON DECAY OF DEEP-HOLE STATES IN ZR-89 POPULATED BY THE ZR-90(HE-3,ALPHA)ZR-89 REACTION AT 102-MEV
Neutron decay of excited hole states populated by the Zr-90(He-3,alpha) reaction at an incident 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 Zr-89 up to 26 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
