Candidate chiral doublet bands in the odd-N ¹³⁵Nd nucleus

For substantial triaxiality, the orientation of the rotational axis determines the geometry of the system. For well deformed nuclei, the rotational bands are built through rotation about an axis that is perpendicular to the symmetry axis. While the tilted bands are obtained by rotation about an axis which is tilted with respect to the principle axis and the rotation is still planar. However, the chiral bands are obtained by rotating about an axis which does not lie in a plane and is, therefore, known as aplanar rotation. Since the first experimental evidence for chiral doublet bands was found in the odd-Z N = 75 isotones, more than 20 experimental candidates have been reported in the A ∼ 100, 130, and 190 mass regions, including odd-odd, odd-A and even-even nuclei
