从18.076-124eV的离解电离阈值测量了H+和H2+产生的绝对截面。主要由Q1里德堡态的自电离引起的H+截面上发生了宽共振。仅产生中性原子的绝对截面是通过使用已公布的光电离产额数据获得的。结果表明，中性氢碎片和电离氢碎片的和产生了一个主要共振，表示跃迁到Q1和Q2Rydberg态。
Absolute cross sections for the production of H+ and H2+ have been measured from the dissociative ionization threshold at 18.076–124 eV. A broad resonance occurs in the H+ cross section caused primarily by autoionization of the Q1 Rydberg states. The absolute cross section for producing neutral atoms only is obtained by the use of published photoionization yield data. It is shown that the sum of the neutral and ionized H fragments produce a major resonance representing transitions into the Q1 and Q2 Rydberg states.
