  Statistics of the single-particle levels in a deformed Woods-Saxon potential
is analyzed in terms of the Poisson and Wigner nearest-neighbor distributions
for several deformations and multipolarities of its surface distortions. We
found the significant differences of all the distributions with a fixed value
of the angular momentum projection of the particle, more closely to the Wigner
distribution, in contrast to the full spectra with Poisson-like behavior.
Important shell effects are observed in the nearest neighbor spacing
distributions, the larger the smaller deformations of the surface
multipolarities.
