The cross-sections of the Si/sup 28/(n, alpha )Mg/sup 25/ reaction for the transition to the ground state and to the first nine excited states of the residual nucleus Mg/sup 25/ were measured as a function of neutron energy. The measurement was made in the neutron energy range 12.15-18.5 Mev, with a beam resolution of about 50 kev from 12.15 to 14.5 Mev, 100 kev from 14.5 to 16.5 Mev, 150 kev from 16.5 to 18.5 Mev. A solid state semiconductor was used both as a target and as alpha -particles detector. The results of the measurements were analyzed with the theory of the compound nucleus recently developed by Ericson; in particular the amplitude and the width of the fluctuations predicted by this theory were calculated. The comparison between the theoretical and experimental values is discussed. (auth)
