Abstract
The neutron-rich, even-even Pd isotopes were studied via in-beam -ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory. Excited states at 499(9), 590(11), and 686(17) keV were found in the three isotopes, which we assign to the respective decays. In addition, candidates for the states at 1164(20) and 1300(22) keV were observed in Pd and Pd, respectively. The resulting systematics are similar to the Xe () isotopic chain and theoretical predictions by the proton-neutron interacting boson model (IBM-2), indicating the magic nature of in the Pd isotopes.
