Özet

The differential cross-sections for the emission of L(f), L(alpha), L(beta) and L(gamma) groups of L X-ray lines from U, Th and Bi have been measured at different angles varying from 45 degrees to 135 degrees at intervals of 15 degrees. The vacancies were created by 59.5 keV gamma-rays from Am-241 source and L X-rays were measured using a Si(Li) detector. It is found that the L(gamma) and L(beta) groups of L X-rays are isotropic, the L(f) and L(alpha) groups are anisotropic in the spatial distribution.
