We find a {Delta}I=4 bifurcation phenomenon in many ground state rotational bands by performing a staggering parameter analysis, which has been employed often for superdeformed bands. We find also that a small modification of the intrinsic state of the interacting boson model wave function in the {ital sd}-boson space, which has been used extensively for ground bands, is able to produce the regular {Delta}I=4 bifurcation pattern. Adding a {ital g} boson, we are able to generate even an irregular pattern in the {Delta}I=4 bifurcation phenomenon, which seems to be observed in some ground bands. {copyright} {ital 1997} {ital The American Physical Society}
