Coriolis-decoupled high-spin E2 bands in odd-A rubidium and krypton isotopes

Heavy-ion reactions have been used to study high-spin bands in odd-A nuclei in the mass A approx. = 80 region. A previously unobserved band of E2 transitions has been assigned to 79Rb. Six reactions were used to rule out other assignments. Bands of E2 transitions have also been assigned to 79Kr and 81Kr. The bands in 79Rb, 79Kr and 81Kr were studied using γ-ray singles, γ-γ coincidence, angular distribution, and excitation function measurements. Relative reaction cross sections were deduced for the 10B + 72Ge and 11B + 73Ge reactions at 40 MeV. The experimental cross sections were in fair agreement with evaporation-model calculations made with the code ALICE
