用调制原子束技术测量了原子氧的电离截面。首先，测量了电子与氧分子碰撞中产生分子氧离子的截面与总离子产生截面的比值。然后确定了电子-分子碰撞中自由氧原子的电离截面与分子离子产生截面的比值。根据已知的分子总电离截面和测量的比率，确定了未知的截面。实验结果与Seaton的计算结果进行了比较。(身份验证)
The cross section for ionization of atomic oxygen was measured by using modulated atomic beam techniques. First the ratio of the cross sections for production of the molecular oxygen ion and for total ion production in collisions of electrons with oxygen molecules was measured. Then the ratio of the ionization cross section of the free oxygen atom and the cross section for production of the molecular ion in electron-molecule collisions was determined. From the previously known total ioni zation cross section of the molecule, and the measured ratios, the unknown cross sections were determined. The experimental results are compared with the calculations of Seaton. (auth)
