Alpha-particle transfer from 6Li to 28Si leading to high excitation of 32S

The excitation of 32S to energies from 24 to 37 MeV followed by its decay to 28Si has been brought about by the two-step alpha transfer reaction 28Si(6Li,d)32S*→α+28Si. A sudden perishing of the decay to the 28Si ground state occurs at 31 MeV of excitation. At about the same energy an increase in the decay to the first excited 2+ state is observed. The yields of 28Si in its ground state or excited to the 21+ and 41+ state prohibit strong fluctuations. This supports the assumption of the existence of states at high excitation in 32S. The results are based on d–α coincidences, which were found to exhibit a strong forward–backward correlation.
