Abstract

The ${}^{12}C$ ( ${}^{12}C$ , ${}^{8}{Be}$ ), ${}^{16}O$ ( ${}^{16}O$ , ${}^{8}{Be}$ ), and ${}^{28}{Si}$ ( ${}^{12}C$ , ${}^{8}{Be}$ ) reactions show final state relative populations which are very similar to the corresponding ( ${}^{6}{Li}, d$ ), ( ${}^{7}{Li}, t$ ), ( ${}^{12}C, α$ ), and ( ${}^{16}O$ , ${}^{12}C$ ) reactions on the same target nuclei. Selective population of final states for ${}^{12}C$ and ${}^{28}{Si}$ targets is accompanied by rapidly fluctuating excitation functions for the ${}^{12}C$ ( ${}^{12}C$ , ${}^{8}{Be}$ ) reactions and much smoother, yet not flat, excitation functions for ${}^{28}{Si}$ ( ${}^{12}C$ , ${}^{8}{Be}$ ). Angular distributions are forward peaked. The ${}^{16}O$ ( ${}^{16}O$ , ${}^{8}{Be}$ ) reaction is not selective, similar to ${}^{16}O ({}^{12}C, α)$ .

[NUCLEAR REACTIONS ${}^{12}C$ ( ${}^{12}C$ , ${}^{8}{Be}$ ) ${}^{16}{O *}$ , measured excitation functions $E_{c . m .} = 17 to 21$ MeV, $σ (θ)$ at 21 MeV; ${}^{16}O$ ( ${}^{16}O$ , ${}^{8}{Be}$ ) ${}^{24}{Mg}^{*}$ ; ${}^{28}{Si}$ ( ${}^{12}C$ , ${}^{8}{Be}$ ) ${}^{32}S^{*}$ , measured excitation functions $E_{c . m .} = 23 to 29$ MeV, $σ (θ)$ at 29.4 MeV.]
