Abstract: | Protons from nuclear reactions induced by 14 MeV neutrons are analysed with solid state detectors. A high background is caused by nuclear reactions in silicon. The application of a telescope with twodE/dx- detectors allows to suppress this background extensively. Proton identification is made by use of a two-dimensional analyser. The telescope is tested by recoil protons with polyethylene. This arrangement may also be used as a neutron spectrometer. The proton spectra from the reaction Ni(n, p)Co in forward direction (0°) and on an angle of 90° are compared. Nuclear temperature and level-density parameter are evaluated from statistical theory plots. The contribution of direct processes is estimated. |
