  The level statistics of SU(3)-SU(3)* transitional region of IBM is described
by the nearest neighbor spacing distribution statistics. The energy levels are
determined by using the SO(6)representation of eigenstates. By employing the
MLE technique, the parameter of Abul-Magd distribution is estimated where
suggest less regular dynamics for transitional region in compare to dynamical
symmetry limits. Also, the O(6)dynamical symmetry which is known as the
critical point of this transitional region, describes a deviation to more
regular dynamics.
