Collective excitations in 88Y

High-spin states in 88Y were excited through the 87Rb(α, 3n) reaction at energies between 30 and 55 MeV. The population of the previously known 8+ and 9+ members of the πg9 2 ⊗ v-1g9 2 multiplet carry most of the total cross section. Above the 8+ state a sequence of 5 levels is observed, which can b...
