“…Similarly to the 759-keV transition, the 484-keV transition should have been detected in Ref. [47] if it was associated with the 85 Zr m . As a summary, the 759-keV, 12(5) s transition follows either the beta decay of 85 Nb m or 85 Mo m .…”

This article reviews the decay studies of neutron-deficient nuclei within the mass region A = 56 − 100 performed at the Ion Guide Isotope Separator On-Line (IGISOL) facility in the University of Jyväskylä over last 25 years. Development from He-jet measurements to on-line mass spectrometry, and eventually to atomic mass measurements and post-trap spectroscopy at IGISOL, has yielded studies of around 100 neutron-deficient nuclei over the years. The studies form a solid foundation to astrophysical rp-process path modelling. The focus is on isomers studied either via spectroscopy or via Penning-trap mass measurements. The review is complemented with recent results on the ground and isomeric states of 90 Tc. The excitation energy of the low-spin isomer in 90 Tc has been measured as Ex = 144.1(17) keV with JYFLTRAP double Penning trap and the ground state of 90 Tc has been confirmed to be the (8 + ) state with a half-life of T 1/2 = 49.2(4) s. Finally, the mass-excess results for the spin-gap isomers 53 Co m and 95 Pd m and implications from the JYFLTRAP mass measurements for the (21 + ) isomer in 94 Ag are discussed.

“…However, the transition could not be associated with the beta decay of 85 Zr m since such an intense transition should have been observed in the detailed beta-decay study of Ref. [47]. At HIGISOL, only the two most intensive peaks at 416 and 454 keV following the 85 Zr beta decay were observed.…”
