Abstract
The neutron decay of high-lying single-particle states in Ni-64, Zr-90 , Sn-120 and (208)pb excited by means of the (alpha,He-3) reaction has been investigated at 120 MeV incident energy using the multidetector EDEN. The characteristics of this reaction are studied using inclusive spectra and angular correlation analysis. The structure located betwe en 11 and 15 MeV in Zr-91, and between 8 and 12 MeV excitation energy in Pb-209 display large departures from a pure statistical decay. The corresponding non-statistical branching ratios are compared with the r esults of two theoretical calculations.
