Wobbling excitations in odd-A nuclei with high-j aligned particles
(2002) In Physical Review C (Nuclear Physics) 65(4).- Abstract
- Using the particle-rotor model in which one high-j quasiparticle is coupled to the core of triaxial shape, wobbling excitations are studied. The family of wobbling phonon excitations can be characterized by: (a) very similar intrinsic structure while collective rotation shows the wobbling feature; (b) strong B(E2;I-->I-1) values for Deltan(w)=1 transitions where n(w) expresses the number of wobbling phonons. For the Fermi level lying below the high-j shell with the most favorable triaxiality gammaapproximate to+20degrees, the wobbling phonon excitations may be more easily identified close to the yrast line, compared with the Fermi level lying around the middle of the shell with gammaapproximate to-30degrees. The spectroscopic study of... (More)

The spectroscopic study of the yrast states for the triaxial shape with -60degrees<γ<0 are illustrated by taking a representative example with gamma=-30degrees, in which a quantum number related with the special symmetry is introduced to help the physics understanding.
