8 Manifestations of Chaos in Quantum Scattering Processes
Fig. 8.1 Total neutron cross section of 238 U versus neutron energy. Peak values of resonances may
not be “true” values due to limitations imposed by the experiment (Garg et al. 1964)
Fig. 8.2 Histogram of
number, N(s), of nearest
neighbor spacings, s, versus
s/D for 238 U. D is the
average spacing. Data for a
sequence of 227 levels are
shown. The solid line is the
Wigner distribution. The
dashed line is the Poisson
distribution (Garg et al. 1964)
