Total (beta)-decay energies and masses of strongly neutron-rich indium isotopes ranging from A = 120 to 129

Beta spectra have been measured and total β-decay energies have been deduced for strongly neutron-rich indium isotopes. Mass separated sources were produced at the OSIRIS on-line separator at Studsvik. By applying β-γ coincidence methods, Qsub(β)-values were determined for isomers of 120-129In. For these nuclei, the atomic mass excess could be derived, allowing the comparison of masses of neutron-rich unstable nuclei with predictions from mass formulae. The mean uncertainty of the experimental mass excesses is 0.12 MeV. The precision of the mass formulae chosen for the comparison varies widely with the mean deviation ranging from 0.12 to 1.39 MeV.
