Abstract

Differential cross sections have been measured for the reaction ${}^{16}O$ ( ${}^{16}O$ , ${}^{12}C$ ) ${}^{20}{Ne}$ leading to the first three states of ${}^{20}{Ne}$ at c.m. energies from 17.5 to 30 MeV and c.m. angles of approximately 62°, 76°, and 90°. The yield curves are characterized by (1) gross structures and narrow structures, and (2) strong angular and cross correlations. It is suggested that these results present direct evidence for shape or quasimolecular resonances in the ${}^{16}O$ + ${}^{16}O$ system.
