Abstract
According to Cooper and Zare [l], spatial distribution of X-ray emission for different magnetic substrates is always isotropic, but in the theoretical calculations of Flugge et al. [2], it is shown that spatial distribution of X-rays is different for different magnetic substrates. The Xrays originating from the states corresponding to J = 1/2 (K shell and L1, L2, M1, M2, subshell, etc.) are expected to be isotropic and those corresponding to state J = 3/2 (L2, M3, M4, subshell, etc.) and J = 5/2 (M5 subshell, etc.) are expected to be anisotropic in their spatial distribution. The angular distributions of ion-induced [3–7] and photon-induced [8–10] L X-rays were investigated for some elements. We have measured differential cross-sections of L shell X-rays from Hg, T1, and Pb at different angles varying from 45° to 135° at 15° intervals.
