High-spin states inKr79populated by theSe78(α, 3n)reaction and interpreted in terms of a quasiparticle-plus-rotor model

Nuclear states of ${}_{}{}^{79}{}_{}{}^{}\mathrm{Kr}$ were studied through the ${}_{}{}^{78}{}_{}{}^{}\mathrm{Se}(\alpha , 3n)$ reaction at an energy of 45 MeV. Excitation functions, $\gamma$-ray angular distributions, and $\gamma -\gamma$ coincidences were performed. Three bands based on the g.s. ($\frac{1}{2^{-}}$), 147.1 keV ($\frac{5}{2^{-}}$), and 129.7 keV ($\frac{7}{2^{+}}$) states were identified. Leading order analysis and quasiparticle-plus-rotor model calculations were performed. A good overall agreement was found between the experimental data and the theoretical predictions.
