Abstract
Direct mass measurements with typical uncertainties of 1-10keV have been performed for the first time for ten neutron-rich isotopes 102, 103Y , 108Nb , 111Mo , 113, 114Tc , 116Ru , 119Rh , and 121, 122Pd . The obtained mass data compared with the 2003 atomic-mass evaluation shows systematic overestimation of binding energies far from stability. The relationship between two-neutron separation energies, nuclear structure and shape changes has been investigated by comparing the experimental data with a theoretical calculation based on the Hartree-Fock-Bogoliubov approximation using modern energy density functionals.
