Abstract

The low lying levels of 98Y have been investigated in the Interacting Boson-Fermion-Fermion Model. A U (5) core (96Sr) has been used and the parameters for the calculations were deduced through studies of the neighbours 97Y ( odd proton), 97Sr (odd neutron) and 96Y (proton-neutron interaction). Thus, insight has been gained into the structure of the spherical states of the nucleus 98Y which lies at the onset of nuclear deformations near A = 100 and which exhibits shape coexistence. It was found that this structure deviates remarkably from the zeroth order classification of multiplets which originate from a coupling of the relevant proton and neutron quasiparticles.
