In this paper, a measurement of the atomic mass and mass excess of are presented. This isotope and were produced at the Maier-Leibnitz Laboratory (MLL) in Munich in the
192 Os(d, α)190 Re and194 Pt(d, α)192 Ir reactions. The Q3D magnetic spectrograph was used to measure the momenta of the α-particle ejectiles in order to reconstruct states in both190 Re and192 Ir. A mass calibration was performed using known energy levels in192 Ir. These measurements were used to obtain a new value of the mass excess of190 Re, −35583 ± 5 keV. The previously known literature value is −35640 ± 70 keV. [ABSTRACT FROM AUTHOR]- Published
