Beta decay Questions

1. Describe how parity violation was experimentally detected in $ ^{60}Co \,\beta$-decay. How was the observed asymmetry in the distribution of emitted electrons explained? [Mains 2005]

2. Differentiate between K-capture and inverse $\beta$-decay. Explain what is internal conversion and how it differs from $\beta$-decay. [Mains 2005]

3. Explain how neutrino was discovered from the $\beta$-decay of radioactive nuclei. [Mains 2002]
