Abstract
An upgraded ion-guide system for the production of neutron-deficient isotopes with heavy-ion beams has been commissioned at the IGISOL facility with an 36Ar beam on a natNi target. It was used together with the JYFLTRAP double Penning trap to measure the masses of 82Zr, 84Nb, 86Mo, 88Tc, and 89Ru ground states and the isomeric state 88Tcm. Of these, 89Ru and 88Tcm were measured for the first time. The precision of measurements of 82Zr, 84Nb, and 88Tc was significantly improved. The literature value for 86Mo was verified. The measured states in 88Tc were compared to shell-model calculations and additional constraints on the spins and level scheme were obtained. The masses of 82Mo and 86Ru have been predicted using the measured masses of their mirror partners and theoretical mirror displacement energies, resulting in more tightly bound nuclei with smaller atomic mass uncertainties than reported in the literature.
