Abstract

The neutron-rich, even-even 122^,124^,126Pd isotopes were studied via in-beam γ-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 21+→0gs+ decays. In addition, candidates for the 41+ states at 1164(20) and 1300(22) keV were observed in 122Pd and 124Pd, respectively. The resulting E_x(21+) systematics are similar to the Xe (Z=54) isotopic chain and theoretical predictions by the proton-neutron interacting boson model (IBM-2), indicating the magic nature of N=82 in the Pd isotopes.

N2 - The neutron-rich, even-even 122,124,126Pd isotopes were studied via in-beam γ-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 21+→0gs+ decays. In addition, candidates for the 41+ states at 1164(20) and 1300(22) keV were observed in 122Pd and 124Pd, respectively. The resulting Ex(21+) systematics are similar to the Xe (Z=54) isotopic chain and theoretical predictions by the proton-neutron interacting boson model (IBM-2), indicating the magic nature of N=82 in the Pd isotopes.
