Abstract：
The chaotic classical single-particle motion in an oblate octupole deformed potential with a non-zero z-component of angular momentum L_z is investigated. The stability analysis of the trajectories shows that with increasing rotation of the system, the unstable negative curvature regions of the effective potential surface decrease, which converts the chaotic motion of the system into a regular one.
