Abstract
The yrast states of 89Y have been investigated using large basis shell model calculation with two different effective interactions defined in different model spaces. The calculated excitation energies have been compared with available experimental data. A satisfactory agreement is observed with the jun45pn interaction in the low-energy region. Whereas the inclusion of neutron-core excitation becomes essential to describe high-energy, high-spin states. Calculation using the snt interaction shows improved agreement in describing these states. The wavefunction and seniority of a few states are discussed.
