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