PSEUDO-SPIN FLIP IN DOUBLY DECOUPLED STRUCTURES AND IDENTICAL BANDS

Unfavored components of doubly decoupled bands are reported for the fi rst time. They can be interpreted as having the pseudo-spin flipped re lative to the orientation in the favored components, i.e. antialigned with respect to the rotation axis. In addition, the differences in con secutive transition energies along the favored and unfavored sequences are strikingly similar among them up to I-pi = 15(+) and 14(+) respec tively This feature arises from a cancellation of differences in align ments and moments of inertia.
