MIXED SYMMETRY STATES IN SAMARIUM ISOTOPES WITH A=146-154 BY USING (IBM-2)

In this work, we used tthe (IBM-2) to study the mixed symmetry state property (MSS) foreven-even146-152Sm isotopes, this model gave a good agreementfor the excited energy levels for the g- band and acceptable for quasi (β and γ) bands, Also identified and emphase some states un certain experimentally, Furthermore it have been studied the mixed symmetry state (MSS) for the states (23 +,24 +,25 +,31 +,11 +) Which received a quick response when changing the Majorana parameters for these isotopes.Well, it was calculated the electromagnetic transition B(E2), B(M1) and mixing ratios
