in terms of the exaxt angular momentum projection, properties of the three dimensional cranked hfb ( 3d - chfb ) states are analyzed quantitatively in the context of the relation between the signature of an intrinsic symmetry and the parity of angular momentum, ( - 1 ) ^ i. we found that the tilted states have favorabl...
