Further Evidence for Shape Coexistence in ⁷⁹Zn^m near Doubly Magic ⁷⁸Ni

ATOMIC MASSES ⁷⁹Zn; measured frequencies, TOF; deduced the excitation energy of the 1/2+ isomer, the bandhead of a low-lying deformed structure akin to a predicted low-lying deformed band, shape coexistence. Comparison with state-of-the-art shell-model diagonalizations, complemented with discrete nonorthogonal shell-model calculations. The time-of-flight ion cyclotron resonance (TOF-ICR) method, the JYFLTRAP double Penning trap at the ion guide isotope separator on-line (IGISOL) facility in Jyvaskyla (Finland), and the multi-reflection time-of-flight mass spectrometer (MR-TOF MS) of ISOLTRAP at ISOLDE at CERN (Switzerland).
