The nuclides ^104–108Sn, ^106–110Sb, ^108,109Te, and ¹¹¹I at the expected endpoint of the astrophysical rp process have been produced in ⁵⁸Ni+^natNi fusion-evaporation reactions at IGISOL and their mass values were precisely measured with the JYFLTRAP Penning trap mass spectrometer. For ¹⁰⁶Sb, ¹⁰⁸Sb, and ¹¹⁰Sb these are the first direct experimental mass results obtained. The related one-proton separation energies have been derived and the value for ¹⁰⁶Sb, S_p=424(8) keV, shows that the branching into the closed SnSbTe cycle in the astrophysical rp process is weaker than expected.
