Ar 2+双分子形成的脉冲质谱研究表明，反应通过氩的三种激发态进行，其激发函数峰值为18，28和65 eV。在动力学研究中，有效的辐射寿命和特定的反应速率已被确定在这些电子能量。观察到的相当大的速率常数（1.3-2.0×10−9 cm 3 molecule−1·sec−1）产生的碰撞直径与通过简单理论考虑3 p5 4d和3 p5 5 p组态中氩原子半径所预测的结果非常一致，这些组态具有与Ar 2+最小出现势14.7 eV相兼容的最低能量。
Pulsed mass‐spectrometric studies of the bimolecular formation of Ar2+ show that the reaction proceeds via three excited states of argon which have excitation functions that peak at 18, 28, and 65 eV. In kinetic studies, effective radiative lifetimes and specific reaction rates have been determined at these electron energies. The rather large rate constants observed (1.3–2.0×10−9 cm3 molecule−1·sec−1) yield collision diameters in good agreement with those predicted by simple theoretical considerations of the radii of argon atoms in the 3p5 4d and 3p5 5p configurations, such configurations being of the lowest energy compatible with the smallest reported appearance potential of 14.7 eV for Ar2+.
