本文报道了低压氖瞬态射频光电流效应的研究结果。由于无极射频放电不存在阴极,因而摒弃了涉及阴极的各种效应。利用这样的装置同时进行了吸收光谱和荧光光谱研究,结果表明高能光子的直接光电离对产生氖Is2→2pk的反常光电流信号起着重要作用。

Experimental results on transient rf optogalvanic effect of Ne at low pressure are presented. Since there is no cathode in a rf discharge, the cathode effects are eliminated, Absorption and fluorescence spectra of the sample obtained simultaneously on such apparatus illustrate that the direct photoionization by high-energy photons plays an important role in the optogalvanic effect.
