The super deformed bands in the even mass isotopes of the A?130 mass region characterized by spin alignment and significant band mixing cases. Accordingly, the theoretical and experimental determination of the spin is so difficult. Therefore, in this work a simple method for the spin proposition of rotational super deformed (SD) bands of some even mass Ce and Nd isotopes has been suggested. It depends on the behavior of the variation of the kinematic (?1) and the dynamic (?2) moment of inertia with the angular frequency. Applying this method a good agreement between the calculated and the corresponding experimental values of the gamma-ray transition energies of the SD bands is obtained.
