Tops-on-top model for triaxial, strongly deformed bands in 164Lu

The triaxial, strongly deformed rotational bands in odd-odd nucleus 164Lu are analyzed based on the "tops-on-top model", which is an extension of the "top-on-top model" to include two valence nucleons in each single-j orbital. It is demonstrated that energy levels of experimental...

Summary:The triaxial, strongly deformed rotational bands in odd-odd nucleus 164Lu are analyzed based on the "tops-on-top model", which is an extension of the "top-on-top model" to include two valence nucleons in each single-j orbital. It is demonstrated that energy levels of experimentally known TSD bands of positive and negative parities are well reproduced. The location of negative parity yrare band is predicted, and also B(E2) and B(M1) values for in-band and out-of-band transitions among the yrast and yrare TSD bands are estimated. It is confirmed that one unit difference in the "wobbling quantum number" corresponds to the same difference in the alignment of rotor angular momentum. Coriolis interaction is effective to fully align single-particle spins both in the yrast and yrare bands.
