Abstract：
Two kinds of siganttre splittings, the △I=1 staggering and the band head splitting, are studied in odd-A superdeformed nuclei in the A-190 mass region. It is shown that the band bead splittings exist in the signature partner bands of some odd-A superdeformed nuclei by means of analysing the experimental M1 transition energies between the partner bands. A possible mechanism is proposed for this phenomenon.
