Neutrons numbers affects the reduced transition probability B(E2) as well as the shape of the nuclide. In this study, to determine how the shape of the nuclide is affected by the changing neutron numbers, reduced transition probability B(E2) and deformation parameter (β2) have been studied for 56Ba isotopes, which have neutron numbers (62-92). Transition probability B(E2) and deformation parameter (β2) have been plotted as a function of neutron number to study the effect of neutron numbers on them. The results showed that the shape of the nucleus is close to a spherical shape when the number of neutrons approaches the magic number.
