Abstract：
Recently, a new digitalized 2-Detector Doppler Broadening Spectrometer is developed. 10 pure metal samples are studied with this system. The results show the relationship between 2-D Doppler broadening spectra and electronic structure of these elements. This article introduces the spectrometer, data analysis,the Doppler broadening of 10 pure metal samples, and the discussion about these results.
