The spectroscopic studies of very neutron-rich nucleus 128Ag have been performed for the first time at the Radioactive Isotope Beam Factory of RIKEN. A new seniority isomer with a half-life of 1.60(7) mu s has been identified and is proposed to have a spin-parity of 16-with a maximally aligned configuration comprising three proton holes in the g9/2 orbital and one neutron hole in the h11/2 orbital. The new level structure in 128Ag is quite well described by shell model calculations without invoking excitations across the Z = 50 and N = 82 shell gaps, and presents a good case of seniority scheme in odd-odd nuclei in the south vicinity of the double-magic nucleus 132Sn. With a classification of various components of the proton-neutron interaction, the inversion of lowest-lying 9-and 10-states between 128Ag and its neighboring isotone 130In is found to be dynamically ascribed to the seniority-nonconserving proton-neutron interaction components. The structure above 10-up to the 16-isomer in 128Ag shows remarkable similarities to seniority structures in the semimagic nuclei 128Pd and 130Cd. These spectroscopic features in 128Ag indicate that the N = 82 shell closure is still robust in silver isotopes.
