We report on a set of high-precision measurements nuclear binding and excitation energies, as well spins, magnetic dipole electric quadrupole moments neutron-rich silver isotopes, 113−123Ag. The were performed using the JYFLTRAP mass spectrometer collinear laser spectroscopy beamline at Ion Guide Isotope Separator On-Line (IGISOL) facility. For first time, we can firmly establish ordering long-lived Iπ=1/2−,7/2+ states in these pin down inversion two levels either A=121(N=74) or A=123(N=76). compare findings to calculations with density functional theory (DFT), from which crucial role that spin-orbit strength time-odd mean fields play simultaneous description electromagnetic binding.
