最近，克努森提出，氧离子-离子中和可能对Ogo 4上观察到的紫外氧夜光提供重要贡献。这个过程的相对贡献相比，由辐射复合，它的结论是，辐射复合应始终占主导地位，除非目前接受的相关速率系数的值是错误的。当F区电子浓度不是异常大时（即，NmF 2 <106 cm−3），这两种机制贡献了相当数量的紫外线发射。它还得出结论，除非某些这些系数被低估，这两种机制将不会提供所观察到的紫外夜光强度。
Recently, Knudsen suggested that oxygen ion-ion neutralization might provide an important contribution to the ultraviolet oxygen nightglow observed on Ogo 4. The relative contribution of this process is compared with that provided by radiative recombination, and it is concluded that radiative recombination should always be dominant, unless presently accepted values of the pertinent rate coefficients are in error. When the F region electron concentrations are not abnormally large (i.e., NmF2<106 cm−3), the two mechanisms contribute comparable amounts of ultraviolet emission. It is also concluded that, unless certain of these coefficients are underestimated, the two mechanisms will not provide the observed intensity of the ultraviolet nightglow.
