据推测，在 1600 A 和 2900 A 之间的高压氩气中观察到的发光带是由于分子离子 Ar2+ 的激发态 Ar2+* 的跃迁所致：初始态是具有 2S-2S0 离子原子渐近线的束缚态，最终态是第一组分子离子态中的两个，其解离为离子原子对 2P-1S0。这一假设解释了该发射带的大多数已知实验数据。辐射跃迁之间的竞争以及α粒子轨道中激发离子和电子之间的猝灭碰撞已经通过实验进行了研究，并根据本假设进行了讨论。还对激发态分子离子和基态分子离子的中和进行了比较。
It is proposed that the luminescence bands observed in high-pressure argon between 1600 and 2900 A are due to transitions involving excited states, Ar2+*, of the molecular ion, Ar2+: the initial state is a bound state having a 2S-2S0 ion-atom asymptote and the final states two of the first set of molecular ion states which dissociate to the ion-atom pair 2P-1S0. This assumption accounts for most known experimental data on this emission band. The competition between the radiative transitions and the quenching collisions between the excited ions and electrons in alpha -particle tracks has been studied experimentally and is discussed in terms of the present hypothesis. A comparison is also made between the neutralisation of excited and ground-state molecular ions.
