Title: Angular distribution of Au and U L x-rays induced by 22.6-keV photons

Abstract

The angular distribution of the L x-ray fluorescent lines from Au and U induced by 22.6-keV x rays from a {sup 109}Cd has been measured. A Si(Li) detector having a resolution of 160 eV at 5.90 keV was used to detect these L lines over the angular range of 70 degree sign -150 degree sign . No strong anisotropy was observed as mentioned by some groups. In the case of Au, a maximum anisotropy of 5% was observed while for U it was within experimental errors (2%). From the angular distribution of the L1 line of Au, the alignment parameter was obtained and its value was found to be 0.10{+-}0.14.
