摘要：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 trapmass spectrometry of thermalized
rare isotopes produced by fast-beam fragmentation. The new Q-values obtained from this data
and the (p,g ) reaction rates from [5] allowed new calculations of the reverse (g ,p) reaction rates
through detailed balance. The impact of our new measurements was shown by varying the Qvalues
within their uncertainties, recalculating the reverse reaction rates, and running rp-process
network calculations.
