Abstract

We report results from neutron coincidences with projectile-like fragments in collisions of 35 MeV/nucleon N14 with Ho165. Quasi-elastic events show a clear left-right asymmetry, decreasing with fragment Z, which gives more high energy neutrons on the side of the beam opposite the detected fragment, while strongly damped events are left-right symmetric. A moving-source fit to the spectra in quasi-elastic events requires a source with a velocity near half the beam velocity and moving on the side of the beam opposite the projectile-like fragment. The fitted temperature and kinetic energy of this source are consistent with previous analyses of charged particle emission data which involved an intermediate-velocity moving source, except that in our case the source is not moving along the beam axis. Recoil effects in the framework of two moving sources cannot account for both the asymmetry and angular distribution observed.
