In recent years, the investigation of wobbling motion of triaxially deformed nuclei has become one of hottest topics in nuclear structure physics. In our work [1], the behavior of the collective rotor in wobbling motion is investigated within the particle-rotor model for 135Pr by transforming the rotational wave functions from the K-representation to the R-representation. The evolution of the wobbling mode in 135Pr, from transverse at low spins to longitudinal at high spins, is illustrated by the azimuthal plot. The coupling schemes of the angular momenta of the rotor (R→) and the high-j particle (j→) for transverse and longitudinal wobbling are obtained from the analysis of R-plots and KR-plots.
