      The paper proposes a scheme to simulate a spectrum of thermonuclear neutrons, which is based on the spectrum factorization with respect to densities describing the anisotropy of reaction products in the center-of-mass system. With such factorization, the Monte Carlo simulation of the spectrum is performed for the selected continuous distributions, rather than separate particles.
      This provides the method stability in selecting and refining a grid for drawing results, improves the monotonicity of results and allows obtaining satisfactory results with a much smaller number of simulated particles.
