Identification of levels in 162, 164Gd and decrease in moment of inertia betwee...
Jones, E.; Hamilton, J.; Gore, P.; Ramayya, A.; Hwang, J.; Lima, A. deFrom prompt ?-?-? coincidence studies with a 252Cf source, the yrast levels were identified from 2+ to 16+ and 14+ in neutron-rich 162,164Gd, respectively. Transition energies between the same spin states are higher and moments of inertia lower at every level in N = 100 164Gd than in N = 98 162Gd. These observations are in contrast to the continuous decrease in the 2+ energy to a minimum at neutron midshell (N ...
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 ...
Shifted identical bands: A new phenomenon
Jones, E.; Gore, P.; Hamilton, J.; Ramayya, A.; Lima, A. de; Dodder, R.; Kormicki, J.; Hwang, J.; Beyer, C.; Zhang, X.; Zhu, S.; Ter-Akopian, G.Abstract The levels in 162Gd were identified in spontaneous fission studies. Its transition energies are remarkably similar to those in 160Gd. From that work, an analysis of yrast bands in even-even proton to neutron-rich Ba to Pb nuclei 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 shi...
