Abstract

The level structure of90Y has been studied using the91Zr(t,α)90Y and89Y(n,γ)90Y reactions. The proton pickup reaction was studied with 17 MeV tritons and a Q3D spectrometer. In the thermal89Y(n, γ)90Y reactionγ-rays from ≈100 to 6,857 keV were observed. In addition to previously known states and configurations, the ten states of theπ(p 3/2)−1 v(d 5/2)1 andπ(f 5/2)−1 v(d 5/2)1 configurations are assigned. Also many other new levels are identified from the (n, γ) data. The 0−state of theπ(f 5/2)−1 v(d 5/2)1 is assigned at 3,130keV. Finite-range shell model calculations suggest that the tensor force is necessary to reproduce the experimentally observed splittings.
