Elastic scattering of35Cl from27Al,58, 62Ni,116, 120, 124Sn and141Pr

Abstract

Elastic scattering angular distributions for35Cl from27Al,58, 62Ni,116, 120, 124Sn and141Pr have been measured at energies between 100 and 170 MeV. Optical model analyses have been performed to determine reaction cross sections, strong absorption radii and grazing angular momenta. The results are compared with the corresponding quantities extracted by means of the Fresnel scattering model. Near the interaction barrier the quarter point method yields reaction cross sections systematically smaller than the optical model results. The interaction radii, however, do not show significant differences or energy dependencies. These radii are compared with trend formulae for interaction radii, and comparisons with fusion radii are made.
