Excitation Function for 16O+24Mg Elastic Scattering at ?c.m. = 90°

Abstract

The e C.m. = 90· excitation function for 160 + 24Mg elastic scattering, which is only sensitive to even partial waves, has been measured for energies 31·6..;; Ec.m . ..;; 45·2 MeV in an attempt to resolve an uncertainty in the sign and magnitude of a proposed parity-dependent term in the 160_24Mg interaction. The data have been analysed by an optical model potential, which includes both a real parity-dependent interaction and an angular momentum-dependent absorptive term. Both the measurements and calculations show some structure but, since this does not correlate with the energies of the even shape resonances in the 160_24Mg interaction, no conclusion can be drawn concerning the sign and magnitude of the parity dependence of the 160_24Mg potential.
