Using experimental data, the Nearest Neighbor Spacing Distribution (NNSD) function for both stable and radioactive nuclei was directly calculated by kernel density estimation (KDE) method and the distance between the obtained function and regular and chaotic limits was determined using Kullback-Leibeller Divergence (KLD) method. The results show that stable nuclei have more regular spectra than radioactive nuclei and nuclei with alpha decay have more irregular spectra than other nuclei. This indicates that stable nuclei have a more symmetrical structure than radioactive nuclei.
