Suppression of the chain nuclear fusion reaction based on the p+11B reaction because of the deceleration of alpha particles

It is shown that a rapid deceleration of alpha particles in matter of electron temperature up to 100 keV leads a strong suppression of the chain nuclear fusion reaction on the basis of the p+B-11 reaction with the reproduction of fast protons in the alpha+B-11 and n+B-10 reactions. The statement that the chain nuclear fusion reaction based on the p+B-11 reaction with an acceleration of B-11 nuclei because of elastic alpha-particle scattering manifests itself in experiments at the PALS (Prague Asterix Laser System) facility is analyzed.
