Basic Nuclear Properties Questions

1. Calculate the spin and parities of the ground states of $ _2^4He$ and $ _{30}^{67}Zn$ nuclei. [Mains 2005]

2. Explain why a neutral particle such as neutron possesses a finite value of magnetic moment, and how it is determined? [Mains 2002]

3. Calculate Binding energy per nucleon of $ _2^4He$ and $^{16}_8O$.

4. Sketch carefully the binding energy per nucleon curve for stable nuclei. Explain its salient features. On the basis of this curve explain why fusion is possible only for low-mass nuclei, whereas fission takes place in heavy nuclei. [Mains 2003]
