Survival of orbiting in ${}^{20}$Ne (7 - 10 MeV/nucleon) + ${}^{12}$C reactions

Abstract

The inclusive energy distributions of fragments with Z $\ge$ 3 emitted from the bombardment of ${}^{12}$C by ${}^{20}$Ne beams with incident energies between 145 and 200 MeV have been measured in the angular range ${\theta }_{lab}\sim$ 10${}^{\circ }$ - 50${}^{\circ }$. Damped fragment yields in all cases have been found to be characteristic of emission from fully energy equilibrated composites; for B, C fragments, average Q-values, $<Q>$, were independent of the centre of mass emission angle (${\theta }_{c.m}$), and the angular distributions followed $\sim$1/sin${\theta }_{c.m}$ like variation, signifying long life times of the emitting di-nuclear systems. Total yields of these fragments have been found to be much larger compared to the standard statistical model predictions of the same. This may be indicative of the survival of orbiting like process in ${}^{12}$C + ${}^{20}$Ne system at these energies.
