Question

Is it possible that in a Coolidge tube characteristic Lα X-rays are emitted but not Kα X-rays?

Open in App

Solution

K_α X-rays are emitted due to the transition of an electron from the L shell to the K shell and L_α X-rays due to the transition of an electron from the M shell to the L shell. If K_α X-rays are not emitted, then the L shell will not be vacant to take the electron from the M shell. Hence, L_αX-rays will not be emitted. Therefore, it is not possible that in a Coolidge tube, characteristic L_α X-rays are emitted but not K_αX-rays.
