X-rays are emitted during

Options

  1. A( , n ) reaction
  2. B(K )-capture
  3. C(n, ) reaction
  4. D( )-emission.

Correct answer

B. (K )-capture

Step-by-step solution

In certain nucleus, the nucleus captures an electron from the (K )-shell (being nearest to the nucleus). The vacancy created is filled up with the electron from the higher shells thereby emitting X-rays. As a result of (K )-electron capture, a proton in the nucleus is converted into a neutron ( (P⁺+e⁻ n ) ).
