A quantum extension of an algebraic sp(4) model is applied to a study of pairing correlations in nuclei with mass 40 ≤ A ≤ 100. While a reasonable overall description of certain nuclear properties is achieved in the nondeformed limit of the theory, the (/-deformation brings forward superior results and plays a significant role in understanding nonlinear effects in many-body physics.
