First β-decay scheme of ¹⁰⁷Nb: New insight into the low-energy levels of ¹⁰⁷Mo

RADIOACTIVITY ¹⁰⁷Nb(β^-)[from U(p, F), E=25 MeV from the K-130 cyclotron at the University of Jyvaskyla, followed by separation of fission fragments using IGISOL-4 for mass separation, and JYFLTRAP Penning trap for isobaric purification]; measured yields of Mo and Nb ions, Eγ, Iγ, γγ- and βγ-coin, γ(Kα x-ray)-coin, half-life of the decay of ¹⁰⁷Nb using a plastic scintillator for β particles and three Ge detectors for low-energy γ rays. ¹⁰⁷Mo; deduced levels, J, π, bands, K-conversion coefficients for three transitions, total conversion coefficient for one transition, multipolarities, β feedings, logft. Systematics of energies of the first and second 1/2+ levels in N=55-71, Z(even)=40-46. Comparison of the experimental γ-ray transition intensities between low-lying levels in ¹⁰⁵Mo and ¹⁰⁷Mo. Discussed the revised energy of the 420-ns isomer.
