چکیده	This study presents the analyses of the statistical correlation of the electric quadrupole transition probabilities in the spherical nuclei. To this aim, the spherical even-even nuclei in the 100 < A < 126 mass region are selected and the electric quadrupole transition rates of different levels in the ground band are determined by the interacting boson model in the U(5) dynamical limit. To consider the statistical correlation of the quadrupole transition rates, a non-parametric kernel density estimation method is used in the framework of nearest neighbor spacing distribution of random matrix theory. Also, the Kullback-Leibeler divergence is used to describe the regular or chaotic properties of considered sequences. The results show the correlation of the electric quadrupole transition probabilities between different levels of the ground band. Also, the correlation increased for such transition that the angular momentum of the initial state of quadrupole transition increased.
