Angular dependence of $L_a/L_l,L_a/L_b/L_a/L_g,L_b/L_g$ intensity ratios of Tl and Au at 59.5 keV

Özet

The angular dependence of $L_{\alpha}/L_l,L_{\alpha}/L_{\beta}/L_{\alpha}/L_{\gamma},L_{\beta}/L_{\gamma}$ intensity ratios of Tl and Au were investigated at 59.5 keV by measuring the L x-ray peaks at different angles. The vacancies were created by 59.5 keV $\gamma$ rays from an $^{241} Am$ 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 $L_l$ and $L_{\alpha}$ groups are anisotropic in the spatial distribution. We compared our results with theoretical values.
