Study Of A 5-Alpha Cluster Candidate With The Ne-22(P,T)Ne-20 And Ne-22(P, He-3)F-20 Reactions

The isobaric nuclei Ne-20 and F-20 were investigated with the Ne-22(p,t)Ne-20 and Ne-22(p, He-3)F-20 reactions using a beam of protons at E-p = 80 MeV. The former reaction was employed to confirm a tentative candidate for the 5-alpha cluster state in Ne-20, while the latter was used to look for T = 2 isobaric analogue partner states in F-20 to states which were already observed above E-x = 20 MeV in Ne-20. The existence of a state which could be considered as a candidate for the 5-alpha cluster state is confirmed here as well as the T = 2 IAS states in Ne-20.
