The inclusive energy distributions of the complex fragments ($3⩽Z⩽7$) emitted from the bombardment of ${}^{12}\mathrm{C}$ by ${}^{20}\mathrm{Ne}$ beams with incident energies between 145 and 200 MeV have been measured in the angular range ${10}^{°}⩽{\theta }_{\mathrm{lab}}⩽{50}^{°}$. Damped fragment yields in all the cases have been found to have the characteristic of emission from fully energy equilibrated composites. The binary fragment yields are compared with the standard statistical model predictions. Whereas Li and Be fragments yields are in agreement with statistical-model calculations, enhanced yields of entrance channel fragments ($5⩽Z⩽7$) indicate the survival of orbiting-like process in ${}^{20}\mathrm{Ne}+{}^{12}\mathrm{C}$ system at these energies.
