Abstract

High-spin states in 80Sr were studied using the 54Fe(28Si,2p) reaction at 90 MeV and the 58Ni(28Si,α2p) reaction at 110 MeV. Prompt γ−γ coincidences were measured from the 54Fe(28Si,2p)reaction using an array of 10 Compton-suppressed Ge detectors. γ-ray linear polarizations were measured in both reactions using three clover detectors as Compton polarimeters. Negative parity has been conclusively assigned to one band and is favored for two others based on the polarization measurements and the observation of six new linking transitions between the bands near their band heads. This evidence supports a picture of strong mixing between low-lying states with negative parity, similar to what has been observed in 82Sr. Directional correlation of oriented nuclei ratios support the spin assignments made in the most recent in-beam study.
