| Abstract: | The neutron energy spectra emitted in the reactions of 33.4MeV/u 17N on 9Be and 197Au targets have been measured at different angles with the time of flight method. The angular distributions were composed of two components: one focused into a narrow angle range around the beam direction and another extended over a large angle region. Integrating the angular distribution， the obtained total cross sections of neutron emission were （15.2±1.7）×10-28m2 and （120±20）×10-28m2 barns respectively for 9Be and 197Au targets. |
