Abstract

The present work demonstrates the application of multi-quasiparticle triaxial projected shell model (TPSM) to investigate the band structures of ⁹⁸⁻¹⁰⁶Ru isotopes. These nuclei, falling in the mass region A ~ 100 of nuclear chart, exhibit a variety of interesting properties including the description of band structures with well developed γ- and 2γ-bands. By performing the exact three-dimensional angular-momentum projection technique used in TPSM, a reliable description of yrast and near yrast bands is presented in detail in the present work. The discussion on the importance of 2-quasiparticle neutron bands with K = 1 and K = 3 has proven to be quite substantial in describing various structural properties of these nuclei. It is reported that the comparison of calculations and experiments yields good agreement and a reasonable description of structure variations, transition rates and many other observed properties of isotopes under consideration has been quite systematically provided.
