TheLRadiation from Sulphur

Abstract

The $L$-emission band from a sulphur target has been studied spectrophotometrically, and the intensity contour of the band has been deduced. The essential features consist of a strong peak at 149 ev, less pronounced structures at about 158 ev, and a broad peak or "tail" around 136 ev, in substantial agreement with previous studies. In contrast with the corresponding bands from the metallic elements of the second row of the periodic table, the drop in intensity on the high energy side of the band occurs gradually. Because of this fact, and perhaps also because of insufficient resolving power, the $L_{\mathrm{II}}$ and $L_{\mathrm{III}}$ edges have not been separated. A tentative interpretation has been given for the main observed features. No trace of the $L_{\mathrm{I}}-L_{\mathrm{III}}$ transition has been found.
