Abstract: The Reflection Asymmetric Shell Model has been generated to include the axial symmetry break. In this new development, the shell model space is spanned by the triaxially-deformed multi-quasi-particle basis. A unified shell model description of the signature inversion, chiral and wobbling bands can be achieved. In the frame work of shell model, the inclusion of the triaxiality, the exact three dimensional projection and up to six quasiparticle configuration mixing make the theory powerful to study the phenomena in highly rotating triaxial nuclei at a new level.
