X-rays are emitted during

A

`alpha`, n reaction

B

K-capture

C

`n, alpha` reaction

D

`beta`-emission

Text Solution

Verified by Experts

The correct Answer is:
C

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^(-)to n)`.
