Abstract :
A method of calculating neutron spectra in the energy range above 3 MeV is presented. Analysis of the pulse height due to the (n, p) and (n, α) interaction in a silicon charged particle detector permits computation of the neutron spectrum by inversion of a matrix whose elements are proportional to the charged particle cross section.
