Frauendorf et al. noted chiral bands can be associated with angular momentum in triaxial nuclei when the total angular momentum is not along any axis.
Chirality is a geometrical concept that derives only from the orientation of the angular momentum with respect to the triaxial shape.
RZ : the rotation about the Z axis, T : Time reversal
