| Abstract: | High spin states of the yrast band in 50Ti, 52Cr, 54 and 46Ti are investigated in a microscopic approach allowing a coupling of rotations, vibrations and quasiparticle excitations. The lowering of the 6+ state in N = 28 nuclei is shown to originate mainly from proton K = 0 two-quasiparticle excitations. Using as a basis the entire pf-shell 8+ and 10+ states can be predicted for 50Ti and 54Fe. |
