Query: Parity violation in reactions with B- and Li- nuclei using polarized
  thermal neutrons   Parity violation in the $(n,\alpha)$ reactions on $^6$Li and $^{10}$B nuclei
and in the $\gamma$-transition between two lowest levels of $^7$Li nucleus is
discussed. It appears that the effects (neutral currents contribution in
particular) are measurable due to the large values of the neutron cross
sections. This holds promise for the theoretical extraction of the constants of
the weak NN potential because of the relative simplicity of the investigated
systems.
