“…The velocity contour maps of the Galilean-invariant differential cross-sections, (d 2 σ/dΩdE)/pc, as a function of the velocity of the emitted protons provide an overall picture of the reaction pattern [12,13,14]. The velocity diagrams of invariant cross-sections in the (v ,v ⊥ ) plane for protons emitted in 20 Ne + 12 C, 27 Al reactions at different bombarding energies have been displayed in Fig.…”

“…To understand the nature of the sources, the proton energy spectra have been fitted using a phenomenological moving source model [13,14,15,16,17,18] where it is assumed that the protons are emitted isotropically in the rest frame of moving sources. As there is evidence of pre-equilibrium component in proton spectra, it has been assumed that protons are emitted from two different sources: (i) equilibrium source having velocity v 0 and (ii) intermediate velocity source having velocity v 1 > v 0 .…”

Inclusive energy distributions for light charged particles (p, d, t and α) have been measured in the 20 Ne (158, 170, 180, 200 MeV) + 12 C reactions in the angular range 10 o -50 o . Exclusive light charged particle energy distribution measurements were also done for the same system at 158MeV bombarding energy by in-plane light charged particle -fragment coincidence. Pre-equilibrium components have been separated out from proton energy spectra using moving source model considering two sources. The data have been compared with the predictions of the statistical model code CASCADE. It has been observed that significant deformation effects were needed to be introduced in the compound nucleus in order to explain the shape of the evaporated d, t energy spectra. For protons, evaporated energy spectra were rather insensitive to nuclear deformation, though angular distributions could not be explained without deformation. Decay sequence of the hot 32 S nucleus has been investigated through exclusive light charged particle measurements using the 20 Ne ( 158MeV) + 12 C reaction. Information on the sequential decay chain has been extracted through comparison of the experimental data with the predictions of the statistical model. It is observed from the present analysis that exclusive light charged particle data may be used as a powerful tool to probe the decay sequence of hot light compound systems.
