Abstract

A rotational band has been discovered in the nucleus ⁶⁴Zn; it extends from spin (12ℏ) to spin (24ℏ), and exhibits strong dipole transitions between its signature partners. In our interpretation, ⁶⁴Zn takes on triaxial deformation (ε ∼ 0.3γ ∼ 30°) at intermediate spin when an f_7/2 proton is promoted across the spherical shell-gap at Z = 28 to the g_9/2 orbital. The situation is parallel to that occurring in the smooth terminating bands in the Sn and Sb isotopes at the Z = 50 shell-gap. The band in ⁶⁴Zn is the first example of a collective band approaching termination in the mass A ∼ 60 region. Crown
