Abstract
In this paper, a measurement of the atomic mass and mass excess of 19075Re are presented. This isotope and 19277Ir were produced at the Maier-Leibnitz Laboratory (MLL) in Munich in the192Os(d, a)190Re and 194Pt(d, a)192Ir reactions. The Q3D magnetic spectrograph was used to measure the momenta of the a-particle ejectiles in order to reconstruct states in both190Re and192Ir. A mass calibration was performed using known energy levels in 192Ir. These measurements were used to obtain a new value of the mass excess of190Re,-35583 ± 5 keV. The previously known literature value is-35640 ± 70 keV.
