Monte Carlo simulation for the evaluation of the concentration, widths and others properties of light nuclei from some samples consisting in a succession of capture and total cross section measurements in neutron transmission experiments has been done. We have analyzed in a computer simulated experiment the cases when a sample contains some light elements, as 6Li and 10B, together with some medium and heavy nuclei. The 6Li and 10B nuclei, for thermal neutrons, have a very high value of (n,É—) cross section and a very small capture cross sections [7]. By using the neutron resonance parameters [7] it was observed that the thermal cross sections values are described mainly by the S-resonances for both nuclei and less by the P-resonances [8,9]. The present computer evaluation is a proposal for experiments on light nuclei data evaluation to the IREN - the new neutron source from the FLNP.
