Abstract

In the present measurements a $^{12}$ C target was bombarded by a $^{4}$ He beam with energies from 14 to 21 MeV and the excitation function measurements for the reactions of the $^{12}$ C $(^{4}$ He, $^{8}$ Be) $^{8}$ Be, $^{12}$ C( $^{4}$ He, $^{12}$ C $[7.65, 0^{+}]$ ) $^{4}$ He, and $^{12}$ C( $^{4}$ He, $^{12}$ C $[9.64, 3^{-}]$ ) $^{4}$ He were obtained using an array of 6 double-sided silicon strip detectors. The excitation functions are used to gain an insight into possible $α$ -cluster structures in $^{16}$ O.
