测量了中性和单电离态钛的能级系统中的粒子数密度。所研究的放电是在氩气或氖作为缓冲气体中操作的高电流空心阴极。测得的动力学和人口的中性物种的温度不同的两个以上的因素。对于金属离子来说，有直接证据表明电荷转移和潘宁碰撞的影响会产生偏离玻尔兹曼分布的结果。在Ar-Ti空心阴极系统中，发现了5s和5 p组态布居数的反转。
Measurements are reported of population densities in the energy level systems of neutral and singly ionised titanium. The discharge under investigation was a high-current hollow cathode operated in argon or neon as a buffer gas. The measured kinetic and population temperatures of the neutral species differ by more than a factor of two. For the metal ions there is direct evidence of the effects of charge transfer and Penning collisions producing departures from a Boltzmann distribution. For the Ar-Ti hollow-cathode system inversion between the populations of the 5s and 5p configurations has been found.
