Fragmentation pattern in sequential emission spectra

Abstract

Coincident light particles and fragments produced in Kr+Au reactions at 27, 44 and 60 MeV/u have been measured with a large solid-angle set-up. Energy spectra of Z=1, 2 and 3 particles sequentially emitted by the slowed-down projectile-like nucleus evolve between an evaporation and a fragmentation pattern, suggesting a saturation in the thermalisation process.

    Citation Excerpt :

    Multi detectors allow multiple source analyzes based on neutron and light charged particle angular and energy distributions in order to identify and characterize the emitting sources of a nuclear process. For example, this approach was used, in the Fermi energy domain, to determine the maximum temperature a nucleus at these energies can reach [6,7]. With the advent of new radioactive, mostly neutron rich, beam facilities, the importance of neutron detection is growing.
