Description

γ rays were measured at several angles in both singles and coincidence modes in the 115Sn(α,nγ)118Te reaction at 15 MeV on a thick target. Multipolarities and mixing ratios were determined from the γ-ray angular distribution analysis. Lifetimes of 11 low- and medium-spin excited states in 118Te were determined from a Monte Carlo Doppler-shift attenuation method analysis of the Doppler broadened line shapes of γ rays deexciting the levels. The results are discussed in comparison with the predictions of the interacting boson model.
