Abstract: Following recent measurements [1,2] of the neutron and photon spectra of two different 241Am Li(a,n)10B source, this paper preliminarily reports on a method based on Monte Carlo simulation in order to obtain the pure and unperturbed 241Am-Li spectrum, hereafter called ideal, one that started within the source material, using the neutron spectrum measured outside the source encapsulations. Various parameters that affect the photon and neutron yields and the energy distributions of these sources were investigated and the theoretical spectrum was calculated and compared to that of Geiger and Van der Zwan [3]. Further work is in progress.
