Theoretical Calculation of Rotational Bands of ¹⁷⁹Pt in the Particle--Triaxial--Rotor Model

Theoretical calculations have been performed for nucleus ¹⁷⁹Pt in the particle--triaxial--rotor model with variable moment of inertia. The obtained energy spectrum agrees with the experimental data quite well. The calculated results indicate that the bands 1/2^- and 7/2⁺ are triaxial deformation bands and originate mainly from the v5211/2^- and v6337/2⁺ configurations respectively.
