    用飞行时间技术测得33.4MeV/u 17N与9Be和197Au靶发生核反应时在不同角度出射的中子能谱。中子角分布包含两种不同组分:聚焦于束流方向的狭窄角分布和扩展在宽角度范围的分布。对能量和角度积分获得对于9Be和197Au靶的发射中子总截面分别为（15.2±1.7）×10-28m2和（120±20）×10-28m2。

    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.
