氖光电流效应中的反常信号与尾部小峰
Anomalous signal and small tail peak observed in neon optogalvanic effect
摘要
本文采用无极射频光电流实验对目前在空阴极中所存在的一些有争议的同题进行讨论.发现在同样气压下射频光电流信号中不存在1S_2-2P_k的反常信号;尾部小峰在射频光电流信号中仍存在,证明与阴极无关.本文用双极扩散效应讨论了尾部小峰的出现规律.
Abstract
Different points of view exist on the mechanism of neon optogalvanio effect in a hollow cathod tube. We have carried out eleotrodeless RF optogalvanio experiments to investigate such mechanism. Experimental results show that there exists no anomalous signal in the RF optogalvanio signal at the same pressure. The small peak on the tail still exsists and has no relation to the cathode. Bipolar diffusion effect is cited to discuss the peak s coourrence.
