A comparison of angular distributions for charge exchange reactions to analogue states in 20Na and 20F

Differential cross sections are presented for the analogue charge exchange reactions 20Ne(3He,t)20Na and 20Ne(t,3He)20F at an incident energy of 33.4 MeV. The angular distributions are very similar for states of the same spin-parity assignment. On this basis, the analogue of the 2646 keV state in 20Na is identified with the 2966 keV state (3+) in 20F.
