Talk:K-alpha
From Wikipedia, the free encyclopedia
The first line of the article suggests both emission and absortion K_alpha are a result of L <- K transitions, this is only the case for absorbtion, K alpha emission would be an L shell electron dropping to a vacant K orbital (such as when a metal sample is bombarded with electrons, a K electron is ejected and the atom relaxes and an x-ray is emmited, such a process occurs in an x-ray tube, for instance). This should be clarrified. 85.211.247.232 15:51, 7 June 2007 (UTC) r_edkins
