A study of Os isotopes chain from (172-194) nuclei is presented .The energy levels , B(E2) transitions , the quadrupole moment of 21+ state and potential energy surfaces are described using the general IBM-1 Hamiltonian. In this chain nuclei evolve from O(6) to SU(3) properties stepwise with increases the atomic mass number. The energy ratio E(Jiπ)/E(21+) for the Jiπ =41+,61+ and 81+ levels for the doubly even Osmium isotopes agreement with both the non axial gamma-soft rotor limit and rotational which behavior were good criterion for the shape transition. The predicted theoretical calculations were compared with the experimental data in respective figures and tables ,it was seen that the predicted results are in a good agreement with the experimental data.
In the framework of IBM calculations (33) new energy levels were determined for 172-194Os
