Аннотация
By employing a beam of reactor fast neutrons, the spectrum of gamma rays up to an energy of 4.6MeV and their angular distributions with respect to the neutron-beamaxis aremeasured in the reaction 89Y(n, n'γ). The multipolarities and multipole-mixture parameters for 34 gamma transitions and the spin–parities Jπ of states excited in this reaction are determined. The lifetimes of the lowest 32 levels of 89Y were measured by the Doppler shift attenuation method, and the reduced probabilities for the respective gamma transitions were calculated. Levels of the Kπ = +5/2+ and Kπ = −7/2+ bands associated with, respectively, prolate and oblate deformation shapes are found in 89Y at low excitation energies.
