Low-energy coexisting band in 154Gd.
A low-energy coexisting band Jpi (Ex keV) 0(+) (1182), 2(+) (1418), 4(+) (1701) is identified in the deformed nucleus, 154Gd. Detailed gamma-ray spectroscopy following the beta decays of 154Eu (J=3), (g,m(1),m(2))154Tb (J=0,3,7) is used to establish this structure. The structure is explained in terms of the pairing and deformation degrees of freedom, a "pairing isomer," which results from the nu[505] upward arrow Nilsson intruder orbital.
