High-j Intruder Orbitals and the $\Delta I$ = 4 Bifurcation in Superdeformed Bands

Abstract

All the known cases of the $\Delta I=4$ bifurcation in the SD bands are analysed in the framework of the microscopic theory suggested by the author [Phys. Rev. C 55 (1997) 1275]. It is shown that the intruder orbitals are of paramount importance to the energy staggering.
