报道了96 MeV中子在氧气中产生轻离子(p、d、t、{sup 3}He和{α})的双微分截面。从20度符号到160度符号以20度符号为步长，在8个实验室角度下测量能谱。给出了数据获取和数据归约的步骤。报道了推导出的能量微分截面和产额截面。实验截面与理论反应模型计算和文献中较低能量下的实验数据进行了比较。测量的质子数据与模型计算的结果相当吻合，而对其他粒子的一致就不那么令人信服了。测量的质子、氚、三子和{α}粒子的产生截面支持在较低能量下的数据所表明的趋势。
Double-differential cross sections are reported for light-ion (p, d, t, {sup 3}He, and {alpha}) production in oxygen induced by 96 MeV neutrons. Energy spectra are measured at eight laboratory angles from 20 degree sign to 160 degree sign in steps of 20 degree sign . Procedures for data taking and data reduction are presented. Deduced energy-differential and production cross sections are reported. Experimental cross sections are compared to theoretical reaction model calculations and experimental data at lower neutron energies in the literature. The measured proton data agree reasonably well with the results of the model calculations, whereas the agreement for the other particles is less convincing. The measured production cross sections for protons, deuterons, tritons, and {alpha} particles support the trends suggested by data at lower energies.
