Abstract
The interplay of pairing is explored for the spectral statistics of nuclear systems with emphasis on the nearest neighbor spacing distributions by employing the kernel density and maximum-likelihood estimation techniques. Different sequences prepared by all the available empirical data for low-lying energy levels of even- and odd-mass nuclei in the 
mass region. A deviation to more regular dynamics is apparent for even-mass nuclei in comparison to the odd-mass ones, and there are suggestions of the effects due to unclosed proton shells on more chaotic dynamics.
