Parameters of emitting sources in Ar-Ni reaction at 77 MeV/u Source
Two-neutron correlation functions as well as single neutron energy spectra were used to determine the parameters of the emitting sources in Ar-Ni reaction at 77 MeV/u. The neutrons were registered in angular ranges 4degrees-22degrees and 55degrees-66degrees. By a choice of the neutron energy range and measurement angles we are able to determine the space-time parameters of the preequilibrium and the quasi-projectile separately. The source velocities and temperatures were determined by fitting the multisource model parameters to the single-neutron inclusive energy spectra. The space-time parameters were extracted from the fit of correlation functions with a Gaussian (space) and exponential (time) distributions.
