Cranking calculations have been performed for many particles in a deformed single-j shell interacting via realistic two-body forces. Although the particle number is conserved in our problem, it can still be treated as a continuous variable. This allows us to consider the diabolic structure of our hamiltonian, which is important in understanding the two-particle transfer reaction. We also discuss the level interaction which determines whether a system will backbend or upbend. We find an analytic solution for the level interaction strength for small deformations and calculate numerical ones for large deformations. These permit a comparison with other models and a general discussion of the AB interaction strength.
