B. Crowell et al., TEST OF PREDICTED GAMMA-STABILITY AT SPINS ABOVE 8(H)OVER-BAR IN ZN-64, Physical review. C. Nuclear physics, 50(3), 1994, pp. 1321-1329
The nucleus Zn-64 is predicted to be gamma unstable at low spin, but g
amma stable at spins of 8h $($) over bar$$ and above. In order to see
if this structural change is manifested in the decay scheme, this nucl
eus has been studied via gamma gamma, recoil-gamma, and recoil-gamma g
amma coincidence techniques using the reaction C-12(Fe-54,2p) at 155 M
eV. Twenty new levels have been observed with spins of up to 12h $$($)
over bar, but no evidence is observed for the predicted onset of gamm
a stability.
