abstract
Mass measurements of N Z nuclei are important for the study of symmetries in nuclear structure, modeling of element synthesis in the rp-process, and fundamental interaction tests. High precision mass measurements of 68Se, 70Se, 70mBr, and 71Br were performed at the Low Energy Beam and Ion Trap Facility (LEBIT) [1,2, 3,4] by Penning trap mass spectrometry of thermalized rare isotopes produced by fast-beam fragmentation. The new Q-values obtained from this data and the (p,) reaction rates from [5] allowed new calculations of the reverse (, p) reaction rates through detailed balance. The impact of our new measurements was shown by varying the Q-values within their uncertainties, recalculating the reverse reaction rates, and running rp-process network calculations.
