Evidence for second-phonon nuclear wobbling.

چکیده
The nucleus 163Lu has been populated through the reaction 139La(29Si,5n) with a beam energy of 157 MeV. Three triaxial, strongly deformed (TSD) bands have been observed with very similar rotational properties. The first excited TSD band has earlier been assigned as a one-phonon wobbling excitation built on the lowest-lying (yrast) TSD band. The large B(E2)(out)/B(E2)(in) value obtainable for one of four observed transitions between the second and first excited TSD bands is in good agreement with particle-rotor calculations for a two-phonon wobbling excitation.

Microscopic Study of Wobbling Motions in Hf and Lu Nuclei
One of the most striking findings in the recent high-spin spectroscopy is the discovery of onephonon, and possibly double-phonon, excitation of the nuclear wobbling rotational bands. In this talk, we first review the properties of observed wobbling motions, and discuss the failure and success of the possible interpretation in terms of the simple rotor model. Then, we further present results of ...
متن کاملPrecession Mode on High-K Configurations: Non-Collective Axially-Symmetric Limit of Wobbling Motion
We have studied the precession mode, the rotational excitation built on the high-K isomeric state, in comparison with the recently identified wobbling mode. The randomphase-approximation (RPA) formalism, which has been developed for the nuclear wobbling motion, is invoked and the precession phonon is obtained by the non-collective axiallysymmetric limit of the formalism. The excitation energies...
متن کاملMicroscopic Description of Nuclear Wobbling Motion — Rotation of Triaxially Deformed Nuclei —
The nuclear wobbling motion in the Lu region is studied by the microscopic cranked mean-field plus RPA method. The Woods-Saxon potential is used as a mean-field with a new parameterization which gives reliable description of rapidly rotating nuclei. The prescription of symmetry-preserving residual interaction makes the calculation of the RPA step parameter-free, and we find the wobbling-like RP...
متن کاملNuclear Wobbling Motion and Electromagnetic Transitions
The nuclear wobbling motion is studied from a microscopic viewpoint. It is shown that the expressions not only of the excitation energy but also of the electromagnetic transition rate in the microscopic RPA framework can be cast into the corresponding forms of the macroscopic rotor model. Criteria to identify the rotational band associated with the wobbling motion are given, based on which exam...
متن کاملEffect of evidence based medicine training in the quality of journal clubs: A road to evidence based journal clubs
Introduction: Journal clubs play an important role in teaching Evidence Based Medicine (EBM). Evidence based journal clubs focus on real problems of the group, and set a minimum level of evidence for articles to be presented, and in the end a clinical bottom line is set to be used in the daily clinical practice. In this article, we have explained our experience in r...
