Quantum mechanism description of plane channeling radiation characteristics
[in Chinese]
Tin radiation characteristics of plane channeling particles are described in terms of quantum mechanics. In the anharmonic approximation the spectrum distribution of the channeling radiation is calculated, comparison with the experiment shows a good agreement.

Indirect observation of high-resolution spectra of neon by means of laser-excited atomic fluorescence spectrometry in a low-resolution detecting system
Wang Songyue, Jin Juguang, Wang Xiulan, and Sun Xiaozhong
In a low-resolution detecting system, the high-resolution spectra of the atomic neon transitions of 2p3-4s1/1 and 2p7-4d3 have been observed indirectly by means of laser-excited atomic fluorescence spectrometry for the first time. It further confirms that the neon line at 5919.037 is identified to the transition of 2p7
