Study of B(E2) Values of Even-Even Isotopes Using Interacting Boson Model-1

The Electric Reduced Transition Probabilities  have been estimated for the even neutron numbers of  isotopes using Interacting Boson Model-1 (IBM-1). The U(5) symmetry,  values, intrinsic quadrupole moments and deformation parameters of even neutron  of  isotopes have been studied. The R 4/2 values of  isotopes have been calculated for the first  and  energy states and thus U(5) limit is identified.
