Question

The nuclear energy levels of mirror nuclei are similar. Using this empirical fact alone, the nuclear force can be said to be independent of which one of the following properties of the nucleons?

• A. Mass
• B. Spin
• C. Charge
• D. Parity

Hint:

The nuclear force is independent of the charge of the nucleons, as shown by the similarity of energy levels in mirror nuclei.

Answer 1

The Correct Option is C

1. Definition of Mirror Nuclei:
Mirror nuclei are pairs of nuclei that differ only in the number of protons and neutrons, with the total number of nucleons (protons + neutrons) being the same. For example, one nucleus might have more protons and the other more neutrons. These nuclei have nearly identical energy levels, suggesting that the nuclear force acts similarly in both cases.

2. Implication on Nuclear Force:
The fact that the energy levels of mirror nuclei are similar suggests that the nuclear force is independent of the electric charge of the nucleons. Instead, it depends on intrinsic properties like mass, spin, and parity.

3. Characteristics of Nuclear Force:
The nuclear force between nucleons (protons and neutrons) is:
- Strong and short-range
- Independent of electric charge
- Dependent on quantum properties like spin and parity

4. Conclusion:
Therefore, the correct interpretation is that the nuclear force is independent of the charge of the nucleons.
