A new phenomenon - shifted identical bands
Jones, E. F.; Gore, P. M.; Hamilton, J. H.; Ramayya, A. V.; Hwang, J. K.; Lima, A. P. deFrom spontaneous fission data in the prompt [gamma]-ray emission of 252Cf, the isotopes 162Gd and 160Sm were identified and the level schemes of 160Gd and 158Sm were extended. From over 700 comparisons of even-even yrast bands from Xe to Os separated by 2n, 2p, [alpha], 4n, 4p, 2[alpha], [alpha]+2n, [alpha]+2p, 2n-2p, and other cases, from the ground state to 8+ and sometimes as high as 18+, 55 ground state shi...
A new phenomenon: shifted identical yrast bands in neighboring even-even nuclei
Jones, E. F.; Gore, P. M.; Hamilton, J. H.; Ramayya, A. V.; Lima, A. P. de; Dodder, R. S.; Kormicki, J.; Hwang, J. K.; Beyer, C. J.; Zhang, X. Q.Identification of the levels in 160Sm and 162Gd in spontaneous fission studies led to the discovery of a new phenomenon, shifted identical bands (SIB). SIBs are yrast bands in neighboring nuclei (a,b) with moments of inertia which are identical when shifted by a constant amount [kappa] = -[Delta]J1/J1, so J1a(1+[kappa])= J1b, from 2+ to 8+ and higher to 16+. Building on that work, an analysis of yrast bands in ...
