Temperatures determined from neutron emission in nucleus-nucleus collisions

Most neutron spectra from 14N+ 165Ho collisions at 35 MeV/nucleon are described by two moving thermal sources, one at a temperature of ≈2.5 MeV and the other of ≈8 MeV. Resonances in gragment-neutron relative velocity spectra are used to determine a temperature from the relative populations of excit...

Description
Summary:Most neutron spectra from 14N+ 165Ho collisions at 35 MeV/nucleon are described by two moving thermal sources, one at a temperature of ≈2.5 MeV and the other of ≈8 MeV. Resonances in gragment-neutron relative velocity spectra are used to determine a temperature from the relative populations of excited states of 13C nuclei. There is a discrepancy with the equilibrium assumption in that the fitted value, ≈1 MeV, does not match that of either thermal source.
