Statistical analysis of partial reduced width distributions
Description
The aim of this study was to develop rigorous methods for analysing experimental event distributions according to a law in chi2 and to check if the number of degrees of freedom ν is compatible with the value 1 for the reduced neutron width distribution. Two statistical methods were used (the maximum-likelihood method and the method of moments); it was shown, in a few particular cases, that ν is compatible with 1. The difference between ν and 1, if it exists, should not exceed 3%. These results confirm the validity of the compound nucleus model

Le but de cette etude est de mettre au point des methodes rigoureuses d'analyse des distributions experimentales d'evenements suivant des lois en chi2, et de verifier si le nombre de degres de liberte ν est compatible avec 1 pour la distribution des largeurs neutroniques reduites. On a utilise deux methodes statistiques (methode du maximum de vraisemblance et methode des moments). On a montre dans quelques cas particuliers, que ν etait parfaitement compatible avec 1. L'ecart entre ν et 1, s'il existe est au maximum de l'ordre de 3%. Ces resultats confirment la validite du modele du noyau composeFiles
