Barrier penetrability and/or deformation effects inCl35induced fusion onNi58,60,62,64

Abstract

Excitation functions for complete fusion have been measured for ${}_{}{}^{35}{}_{}{}^{}\mathrm{Cl}$ projectiles on ${}_{}{}^{58,60,62,64}{}_{}{}^{}\mathrm{Ni}$. Deviations from the predictions of the sharp cutoff model are observed and compared with calculations based on the formalism of Wong. In this picture tunneling and static deformation of target and projectile can explain the experimental data in the barrier region.
