Abstract

The available evidence on the spin-parity assignments for the 3176 and 3646 keV levels of 44Ti is reviewed. The results of new studies of the decay γ-rays of the 4.22 MeV resonance in the 40Ca(α, γ) 44Ti reaction are presented. Angular distribution fits and strength arguments are used to establish J(3176) = 3 and J(3646) = 4, with the two levels having the same parity. If the 46Ti(p, t) 44Ti reaction excites only states of natural parity, then J π (3176) = 3 − and J π (3646) = 4 −.
