Journal ArticleDOI
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
Fluctuation analysis of rotational spectra
Thomas Døssing,B. Herskind,S. Leoni,S. Leoni,A. Bracco,Ricardo A. Broglia,Ricardo A. Broglia,Masayuki Matsuo,Enrico Vigezzi +8 more
TL;DR: In this paper, two-and higher-fold coincidence spectra emitted from rotating nuclei are analyzed with respect to the count fluctuations, and the analysis of the fluctuations will be shown to be instrumental to gain insight into the phenomenon of rotational damping.
Journal ArticleDOI
Interactions between a multitude of rotational bands in well deformed odd nuclei: A new method for spin and parity assignment
G.B. Hagemann,H. Ryde,P. Bosetti,A. Brockstedt,H. Carlsson,L.P. Ekström,Anders Nordlund,R.A. Bark,B. Herskind,S. Leoni,S. Leoni,A. Bracco,F. Camera,S. Frattini,M. Mattiuzzi,Benedicte Million,C. Rossi-Alvarez,G. de Angelis,D. Bazzacco,S. Lunardi,M. De Poli +20 more
TL;DR: Using the (18O,5n) 163Er reaction, a multitude of rotational bands have been established with firm spin and parity assignments in 163Er as mentioned in this paper, and the interaction strength varies between ∼ 1 and ∼ 50 keV with many of the values in the range 10-15 keV.
Journal ArticleDOI

TL;DR: In this paper, the rotational damping of rotational motion applying rotational plane mapping (RPM) method is presented and discussed, where the authors extract the distribution of the rotation transition strength from an analysis of the shape of the central valley of two-and three-dimensional γ-ray spectra.
Journal ArticleDOI
Observation of an intense quasicontinuum of superdeformed rotational transitions in 143Eu.
TL;DR: F Fold distributions, angular anisotropies, moment of inertia determinations, and lower limits of lifetimes as a function of the rotational frequency show that the bump originates from highly collective rotationally damped transitions generated by superdeformed states.
