Abstract

The 0° differential cross sections for the ${}^{11}B$ (α,n $)^{14}$ N, ${}^{12}C$ (α,n $)^{15}$ O, and ${}^{24}{Mg}$ (α,n $)^{27}$ Si reactions were measured at $E_{α}$ =47.4 MeV. Well-known states of high spin in ${}^{15}O$ were used to determine the excitation energy of states in ${}^{14}N$ and ${}^{27}{Si}$ . Several states of high excitation energy in these nuclei are reported. The energies of these states are consistent with particle-hole weak coupling calculations for high spin states. Comparisons with previous experiments are made where possible.
