Ground-state and decay properties of neutron-rich ¹⁰⁶Nb

RADIOACTIVITY ¹⁰⁶Nb(β^-)[from ²⁵²Cf(SF), CARIBU radioactive-ion-beam facility at ANL, followed by mass separation and measurement using Multi-Reflection Time-of-Flight (MR-TOF) mass separator and Canadian Penning Trap (CPT)]; measured CPT spectra, Eγ, Iγ, βγγ-coin, half-life of ¹⁰⁶Nb decay using five HPGe clover detectors, and a plastic scintillator at the X-Array and SATURN decay-spectroscopy station. ¹⁰⁶Mo; deduced levels, J, π, apparent β feedings, range of logft values, configurations. ¹⁰⁶Nb; discussed spin, parity and configurations of the ground state. Comparison with earlier experimental results.

ATOMIC MASSES ¹⁰⁶Nb; measured cyclotron frequency using the Phase-Imaging Ion-Cyclotron-Resonance (PI-ICR) technique, CPT spectra; deduced mass excess. Comparison with previous measurement, and with AME 2016 evaluation.
