Abstract

Experimentally, under laboratory conditions in the nitrogen acoustic plasma in the region of the forbidden lines at 654.81 and 658.36 nm, a spectral emission line of high intensity was obtained (up to 17 stronger than the neighboring lines of the first positive system of nitrogen). The results were obtained both in pure low-pressure nitrogen acoustic plasma (several hundreds of Pa) and various mixtures containing nitrogen, including the CO2 : N2 : He = 1 : 1 : 8 mixture. The results obtained are explained by the acoustic plasma state of the discharge and an analog of Rahman scattering, which remove some of the quantum mechanical prohibitions. The possible influence of the Coriolis force is also considered.

实验室声学等离子体中禁止跃迁时产生的辐射
摘要在实验室条件下,在氮声等离子体中的 654.81 和 658.36 nm 禁线区域,实验获得了一条高强度的光谱发射线(比氮第一正系的邻近线强达 17)。这些结果是在纯低压氮声等离子体(几百帕)和各种含氮混合物(包括 CO2 : N2 : He = 1 : 1 : 8 混合物)中获得的。放电的声等离子体状态和拉赫曼散射类似物可以解释所获得的结果,它们消除了量子力学的一些限制。此外,还考虑了科里奥利力可能产生的影响。
