Abstract：
The signature-dependence of B(M1)-values and dynamical quadrupole moments Q ⁽¹⁾and Q ⁽²⁾after the band-crossing are investigated by meams of the extended particle-rotor model.The calculated values are in qualitative agreement with the measured data.It was noted that in ¹⁵⁹Tm the γ-value is quite different before and after the band-crossing.
