A study of isobaric analogue resonances in the Yb isotopes

Energy Levels in175Yb from Primary Transitions in the Thermal Neutron Capture Reaction

“…The same arguments as given above may also be applied to the 5/2+ spin assignment given by Breitig [7] to the 1368 keV level but here the primary transition is relatively intense which makes the 512-assignment to the 1368 keV level somewhat dubious. Whineray et al [5] propose this level to be a close doublet containing the 1,'2-~ and 312.-members of the 1/2+ [651] band. The spectrum obtained in the present work has no sign of doublet structure as regards the direct transition to the 1368 keV level.…”

“…The (d, p) and (d, t) reactions used for identification of the rotational structure in lT5Yb by Burke et al [4] have recently been complemented with high resolution stripping reactions by Whineray et al [5] which have allowed a tentative identification of a rotational band based on the 1'2-[651] orbital in 175Yb.…”

Systematics and Fine Structure of Coulomb Displacement Energies

“…(3) and the experimental displacement energies to calculate 6. The results 6 A for Nd, Er, Yb, 24 and Hf 16 isotopes are given in Table II and compared with parameters 6 R from reorientation experiments, 25 6 Q from Coulomb excitation, 26 6 p from muonic x-ray studies 27,2 and dp, from inelastic proton scattering. 29,30 Where no values are available from other experiments we can compare the parameters with values for neighboring nuclei within the difference given by the single-particle estimate.…”
