Abstract

The

{}^{28}{Si} (α, {}^{2}{He}) {}^{30}{Si}

reaction is found to be highly selective in the population of high-spin states. Under the assumption of (simple) shell-model wave functions the angular distributions can be well described by distorted-wave Born approximation calculations with an optical-model parameter set identical to that used in the analysis of the

{}^{28}{Si} (α, d) {}^{30}P

reacti at

E_{α} = 50

MeV. Two previously unobserved states at

E_{x} = 8.93 and 10.64

MeV are suggested to both have

J^{π} = 6^{+}
