Mass measurements of neutron-deficient radionuclides near the end-point of the rp-process with SHIPTRAP

Abstract : Direct mass measurements of nuclides near to the supposed end-point region of the astrophysical rp-process were performed at SHIPTRAP, the Penning trap mass spectrometer at GSI Darmstadt. The masses of 24 nuclides were measured with relative uncertainties between 5 $^{.}$ 10$^{-8}$ and 2 $^{.}$ 10$^{-7}$ . Three of them, $^{107}$Sb , $^{111}$I and $^{112}$I , were determined experimentally for the first time. The data analysis and mass evaluation are presented in detail.
