How would you figure out wht-0 j+ujbr2 cuico-k+ am)fn f-lh lines in an X-ray spectrum correspond to $K_\alpha, K_\beta, L_\alpha$ etc., transitions?




参考答案:
To figure out which lines in an X-ray spectrum correspond to which transitions, you would use the Bohr model to estimate the differences in the sizes of the energy level jumps that the falling electrons will make. Then, you just need to match the n = 2 $ \rightarrow$ n = 1 energy to the $\text{K}_\alpha$
line and the n = 3 $ \rightarrow$ n = 1 energy to the $\text{K}_\alpha$ line and the n = 3 $ \rightarrow$ n = 2 jump energy to the $\text{K}_\alpha$ line and so on.
