Description
High-spin states of $^{67}$Ga have been studied via the $^{58}$Ni($^{12}$C, 3p)$^{67}$Ga fusion-evaporation reaction at a beam energy of 50.4 MeV. Three negative-parity bands and three positive-parity bands in $^{67}$Ga are established. The observation of one new $E3$ transition linking the positive-parity $\pi 1g_{9/2}$ band and negative-parity $\pi 2p_{3/2}$ band provides evidence of octuple correlations in $^{67}$Ga. The characteristics of octuple correlations in the $^{67}$Ga are discussed in terms of the reflection-asymmetric triaxial partical rotor model and microscopic relativistic mean field+Bardeen-Cooper-Schrieffer model.
