Neutron dosimetry and spectrometry with Bonner spheres. Working out a log-normal reference matrix
Description
From the experimental and theoretical studies made upon the BONNER's spheres System with a I6Li(Eu) crystal and with a miniaturized 3He counter we get the normalized energy response functions R*sub(i)(E). This normalization is obtained by the mathematization of the Resolution Function R*(i,E) in the Log-Normal distribution hypothesis to mono energetic neutrons given in April 1976 to the International Symposium on Californium 252. The fit of the Log-Normal Hypothesis with the experimental and Theoretical data is very satisfactory. The parameter's tabulated values allow a precise interpolation, at all energies between 0.4 eV and 15 MeV and for all spheres diameters between 2 and 12 inches, of the discretized R*sub(ij) Reference Matrix for the applications to neutron dosimetry and spectrometry

A partir des etudes experimentales et theoriques effectuees sur le Systeme des Spheres de BONNER avec un cristal I6Li(Eu) et le compteur miniaturise 3He developpe du CEA nous obtenons les fonctions de reponse en energie des spheres R*sub(i)(E) normalisees. Cette normalisation est effectuee par la mathematisation de la Fonction de Resolution R*(i,E) dans l'hypothese des distributions Log-Normales aux neutrons monocinetiques donnee en Avril 1976 au Congres International sur le Californium 252. L'accord de l'hypothese Log-Normale avec les donnees experimentales et theoriques est tres satisfaisant. Les valeurs que nous donnons tabulees des parametres permettent une interpolation precise, a toute energie entre 0,4 eV et 15 MeV et pour tous les diametres des spheres entre 2 et 12 pouces, de la Matrice de Reference discretisee R*sub(ij) en vue des applications a la dosimetrie et a la spectrometrie neutroniquesFiles
