High-precision mass measurements and production of neutron-deficient isotopes using heavy-ion beams at IGISOL

ATOMIC MASSES ⁸²Zr, ⁸⁴Nb, ⁸⁶Mo, ⁸⁸Tc, ^88mTc, ⁸⁹Ru; measured cyclotron frequencies, time-of-flight, and mass excesses using time-of-flight ion-cyclotron resonance (TOF-ICR), and phase-imaging ion-cyclotron resonance (PI-ICR) techniques at the University of Jyvaskyla accelerator laboratory; deduced S(2n), S(2p) and neutron-pairing gap energies. ⁸²Mo, ⁸⁶Ru; predicted mass excesses using the measured masses of their mirror partners and theoretical mirror displacement energies. Comparison with AME-2016 values, and with other recent measurements. ⁸⁸Tc; deduced levels, J, π of the ground state and isomer, and compared with shell-model predictions.

NUCLEAR REACTIONS Ni(³⁶Ar, X)⁸²Zr/⁸⁴Nb/⁸⁶Mo/⁸⁸Tc/^88mTc/⁸⁹Ru, E=222 MeV; measured reaction products and yields using the HIGISOL system, mass separated using a radio-frequency sextupole ion guide (SPIG), and injected into the double-Penning-trap mass spectrometer JYFLTRAP at Jyvaskyla.
