This is because electrons in the n = 2 L-shell are nearer to the n = 1 K-shell. Hence there will be greater probability that the vacancy in the K-shell will be filled by an electron from the L-shell rather than the n =3 M-shell.


By nadeemimi Answered 5 years ago

The transition probability of an electron to jump from L shell to K shell is higher than that of M shell to K shell. Since the L shell electron can have two different energy levels, the K alpha line will be a doublet. A transition from either of these two levels to the K shell level creates two lines. Transitions can take place from the 2p to 1s but not from 2s to 1s. Thus the K alpha have greater intensity than K beta.

The K alpha has the higher intensity than k beta because the probability that the X-rays will cause a transition from n=1→N falls with increasing N.
