In this paper, we have been studied the Osmium even-even isotopes chain from 178 to 182 nuclei which presented to have more information about their properties. The available of experimental data for each isotope under study has been used to calculate the ratios of and , the curve of the as a function of spin (E-GOS curve) and the back- bending curve , and compared with the standard values for each limit, the rotational , the gamma - soft and vibrational . This study show as that, these nuclei have many dynamic symmetries, which begin close to the critical point limit for isotope, and the isotopes are transitional symmetry to . However, the isotope goes to the vibrational limit at high spin. On other hand isotope goes to rotational properties .
