Description
The neutron decay of the continuum in 90Zr and 124Sn, excited by inelastic scattering of 84A MeV 17O ions in the range from 1.5 to 4.5 circle, has been measured. Statistical decay was found to dominate the excitation-energy interval studied, up to about 50 MeV. In the excitation-energy interval from the neutron threshold up to about 35 MeV a distinct direct-decay component to the hole states in 89Zr and 123Sn was observed. In addition, a decay pattern resembling pre-equilibrium decay was observed for 90Zr. In the excitation energy spectrum of 90Zr gated by low-energy (< 2.5 MeV) neutrons, indications of a resonance structure is observed at about 27 MeV. ((orig.))
