Total β-decay energies and masses of tin, antimony and tellurium isotopes in the vicinity of 50132Sn82

Experimental β-decay energies for short-lived isotopes of tin, antimony and tellurium are presented. Mass-separated sources were produced at the on-line isotope separator OSIRIS. By applying β-γ coincidence methods, total β-decay energies have been determined for the following nuclides: 127-131Sn, 128130131134Sb and 134135Te. The atomic mass excess has been derived for these nuclei, and comparisons are made with mass formula predictions. (Auth.)
