摘要: Abstract The non-collective and collective high-spin configurations in selected A ∼ 90 ( Z = 42–45, N 46–49) nuclei are analysed within the configuration-dependent shell-correction approach using cranked Nilsson potential. With this method, various features, such as shape coexistence, changes, band termination superdeformation studied along yrast line. We concentrate on 43 89 Tc 46 nucleus a representative example, while other treated more schematic way. specific feature of under study is high-energy cost associated with building states having an angular momentum higher than what can be obtained from valence particles.
