Evidence for the wobbling mode in nuclei.
S. W. Ødegård,S. W. Ødegård,Gro Hagemann,D. R. Jensen,M. Bergström,B. Herskind,G. Sletten,S. Törmänen,J. N. Wilson,P.O. Tjøm,Ikuko Hamamoto,K. M. Spohr,H. Hübel,Andreas Görgen,G. Schönwasser,A. Bracco,S. Leoni,A. Maj,C. M. Petrache,Piotr Bednarczyk,D. Curien +20 more
TL;DR: Evidence is presented for the assignment of the excited T SD band as a wobbling mode built on the yrast TSD band, based on comparisons to new calculations in which an aligned particle is coupled to a strongly deformed triaxial rotor.
Journal ArticleDOI
One- and two-phonon wobbling excitations in triaxial 165Lu
G. Schönwaßer,H. Hübel,G.B. Hagemann,P. Bednarczyk,G. Benzoni,A. Bracco,P. Bringel,R. Chapman,D. Curien,J. Domscheit,B. Herskind,D. R. Jensen,S. Leoni,G. Lo Bianco,W. C. Ma,A. Maj,A. Neußer,S. W. Ødegård,C. M. Petrache,D. Roßbach,H. Ryde,K.H. Spohr,Amrendra K. Singh +22 more
TL;DR: In this article, two new excited rotational bands have been discovered with features similar to a previously known triaxial superdeformed band in the Lu-165 nucleus, and they belong to a family of wobbling excitations with phonon numbers n(w) = 0, 1 and 2.
Journal ArticleDOI

TL;DR: The nucleus 163Lu has been populated through the reaction 139La(29Si,5n) with a beam energy of 157 MeV and three triaxial, strongly deformed (TSD) bands have been observed with very similar rotational properties.
Journal ArticleDOI
Critical temperature for quenching of pair correlations
A. Schiller,A. Bjerve,M. Guttormsen,Morten Hjorth-Jensen,F. Ingebretsen,E. Melby,S. Messelt,John Rekstad,Sunniva Siem,S. W. Ødegård +9 more
TL;DR: In this article, the nuclear heat capacity is deduced within the framework of the canonical ensemble, which exhibits an S-formed shape as a function of temperature, interpreted as a fingerprint of the phase transition from a strongly correlated to an uncorrelated phase.
Journal ArticleDOI
Radiative strength functions in Mo 93 − 98
Magne Guttormsen,R. Chankova,U. Agvaanluvsan,E. Algin,L. A. Bernstein,F. Ingebretsen,T. Lönnroth,S. Messelt,G. E. Mitchell,G. E. Mitchell,John Rekstad,A. Schiller,Sunniva Siem,A. C. Sunde,A. Voinov,A. Voinov,S. W. Ødegård +16 more
TL;DR: The soft pole is present at all initial excitation energies in the $5\ensuremath{-}8\text{-}}\mathrm{MeV}$ region as mentioned in this paper.
