Abstract

The production of ${}^{4}{He}$ , Li, ${}^{7}{Be}$ , ${}^{9}{Be}$ , B, C, N, O, and F has been studied in the reaction 90-MeV ${}^{3}{He}$ + ${}^{nat}{Ag}$ . Although the yields of the heavier elements are orders of magnitude less than for ${}^{4}{He}$ , the energy spectra, charge, and angular distributions indicate that an equilibrium statistical process is responsible for the production of these heavy nuclei in the backward hemisphere.
