The correct Answer is:
To solve the question "X-rays are emitted during", we need to analyze the options provided and understand the processes involved in each. ### Step-by-Step Solution: 1. **Understanding the Processes**: - **Alpha and Neutron Reaction**: This involves the emission of alpha particles and neutrons from a nucleus, which typically does not produce X-rays. - **K Capture (Electron Capture)**: This is a process where a proton-rich nucleus captures an inner-shell electron (usually from the K shell), converting a proton into a neutron. This process can lead to the emission of X-rays. - **Beta Emission**: This involves the transformation of a neutron into a proton (or vice versa) with the emission of beta particles (electrons or positrons), and does not typically result in X-ray emission. 2. **Identifying the Correct Process**: - Among the options, K capture is the only process that results in the emission of X-rays. When an inner-shell electron is captured, the atom becomes unstable, and as outer electrons fill the vacancy left by the captured electron, X-rays are emitted. 3. **Conclusion**: - Therefore, the correct answer is that X-rays are emitted during **K capture** (or electron capture). ### Final Answer: X-rays are emitted during **K capture**. ---
