Rotation-particle coupling and the triaxiality in ¹⁶⁷Lu

The study of shape of nuclei is an important and interesting subject in the area of nuclear physics. The changes in shape with atomic number provide rich information about the interplay between collective and underlying shell structure of nuclei. Nuclei in the region of 70 ≤ Z ≤ 80 and 82 ≤ N ≤ 126 exhibit interesting features related to shape change from spherical to prolate and then oblate. An odd-proton system ¹⁶⁷Lu, which lies in the range of Z and N mentioned above and find this nucleus as triaxial in shape have been studied. The modified particle-rotor model (MPRM) calculations were performed to study the negative parity yrast band in ¹⁶⁷Lu
