Abstract
The differential cross-sections of L X-ray induced in In, Sn, Sb, and Te have been measured at different angles from 94° to 170° at intervals of 9°. Measurement have been performed with a Si(Li) detector using 5.96 keV photons as the excitation source. It is seen from the results concerning heavy elements that L α peaks show anisotropic emissionn while L β and L γ peaks are emitted isotropically.
