Abstract

Neutron spectra in coincidence with fragments have been observed in 14N-165Ho collisions at 490 MeV. Contributions to the spectra from excited light fragments are very pronounced when the fragments detector and the neutron detector are in colinear geomwtry. Relative velocity spectra then reveal that neutron decay of a single, well-known excited state dominates. In inclusive spectra of neutrons or protons these effects are still present and may not be disregarded.
