High-spin states in68Ga

High spin levels in 70Ga via 68Zn(α, pnγ) 70Ga

“…3, 4). [12]) that an evaporated neutron carries out 1%, we find the difference (10 h -6 h) -I h = 5 h for the evaporated proton, which will be too much for one proton ejected with the 6 MeV Coulomb barrier energy.…”

“…66Zn(a, pny) reactions [12]. So it seems reasonable to hope to reach high spin states in 70Ga via 68Zn(a, pny)7oGa at Ea ~ 30 MeV.…”

“…The assignment confirms the J = 8 suggestion for the 2 602.0 keV state which may be described by the ((nlg9/2) (vlg9/2))8 configuration. The [12] where such states have been described by a 67 Ga core plus a vg9/2 neutron.…”

Calculations of the energy spectra of Zn, Ga, and Ge isotopes by the shell model

“…They assigned 2 + and 3 + to the members of the doublet whose splitting was assumed to be less than lkeV. Morand et al [37] confirmed the 3 + component of the doublet but failed to separate the other. The present calculation predicts an extra 2 + level in the vicinity of the 3~-level.…”

“…The results of the earlier experiments are compiled in Reference 32. Recently Morand et al [37] performed 65Cu(cx, n 7) and 66Zn(~,p nT) experiments. They confirmed previous spin-parity assignments to lower levels and proposed new assignments to higher levels.…”
