Study of Nuclear States in 186Re Excited by the (n, y)-ReactionPrompt and delayed y-y-coincidences were measured after slow neutron capture in lSSRe by use of Ge(Li)-detectors. New isomers were found at 99.4 keV (7"1/2 = 27 ___ 7 ns) and at ~ 330 keV (T1/2 = 17.4___ 0.7 ns). The evaluation of coincidence data established 10 rotational bands with band heads below 700 keV. The level scheme is discussed in detail: Nilsson assignments are proposed for the band configurations, and calculations of Coriolis mixing and 7-transition probabilities are presented which reproduce the experimental level energies and transition intensities very satisfactorily.

“…Our result should also stimulate additional nuclear structure calculations for 183W with the aim of understanding the mechanism which is responsible for the anomalously small magnetic moment and for the giant hyperfine anomaly. Preu interpretations of the magnetic moment [29,30] and recent nuclear structure calculations [31] should certainly be refined and extended. Finally the model of Fujita and Arima should be entended to deformed nuclei.…”

Spin-echo measurements on lssW were performed with dilute alloys of W (0.1, 0.25, 0.5 and 1 at %) in Fe. The result for the hyperfine field: This is the first case of a very large hyperfine anomaly in electronic hyperfine fields which is not caused by the pathological cancellation of orbital and spin magnetism in jackknife Pl/2 or d3/z single proton configurations.A detailed discussion shows that the large hyperfine anomaly may be related to the anomalously small magnetic dipole moment of ~S3W. Our result should stimulate further theoretical work with the aim to understand this magnetic moment as well as the giant hyperfine anomaly.

The ground-state band of 159Tb has been Coulomb excited up to spin 23/2 by 151-MeV 4~ions. The lifetimes of the 9/2 to 23/2 levels have been determined by combining results obtained with the RD and DSA methods, the E2/M1 mixing ratios for AI=I transitions have been measured using angular correlation techniques and the branching ratios for the levels up to spin 17/2 have been determined. The energies of the levels and the reduced M1 and E2 transition probabilities for their decay have been compared with the predictions of the rotational model, without and with AK= 1 admixtures. No satisfactory agreement could be achieved for all available experimental data simultaneously.
