  Neutron emission spectra (NES) of $^{232}$Th+n interaction provide strong
evidence of angular anisotropy of secondary neutron emission, another evidence
might be predicted in $^{232}$Th%(n,F)% prompt fission neutron spectra (PFNS).
In case of NES observed angular anisotropy is presumably due to angular
dependence of elastic scattering, direct excitation of collective levels and
preequilibrium emission of (n,nX) neutrons. In $^{232}$Th+n direct excitation
data analysis, ground state band levels are coupled within rigid rotator model,
while those of beta bands, gamma bands and octupole band theta are coupled
within soft deformable rotator model. NES of $^{232}$Th+n at En of 6, 12, 14,
18 MeV exhaustively described. The net effect of these procedures for En up to
20 MeV is the adequate approximation of angular distributions of
$^{232}$Th$(n,nX)$ first neutron inelastic scattering in continuum, which
corresponds to U of 1.2-6 MeV excitations of $^{232}$Th.
  The contribution of $^{232}$Th$(n,F)$ PFNS to the NES is exceptionally low.
PFNS anisotropy occurs because some portion of $(n,nX)$ neutrons might be
involved in exclusive prefission neutron spectra. In $^{232}$Th$(n,xnf)$
reactions PFNS demonstrate different response to forward and backward (n,xnf)
neutron emission relative to the incident neutron momentum, when compared with
$^{235}$U$(n,xnf)$ or 239Pu(n,xnf) reactions. Average energy of (n,xnf)
neutrons depends on the neutron emission angle theta, i.e. fission cross
section, prompt neutron number and total kinetic energy are shown to vary with
the angle theta as well. Exclusive neutron spectra ($n,xnf)$ at theta equal to
90 degrees are consistent with observed $^{232}$Th$(n,F)$ and
$^{232}$Th$(n,xn)$ reaction cross sections within En from 1 to 20 MeV energy
range.
