MEDIUM
Before the neutrino hypothesis, the beta decay process was thought to be the transition,
np+e¯
If this was true, show that if the neutron was at rest, the proton and electron would emerge with fixed energies and calculate them. Experimentally, the electron energy was found to have a large range.
EASY
Two nucleons are at a separation of one fermi. Protons have a charge of + 1.6 × 10-19 C. The net nuclear force between them is F1, if both are neutrons ,F2 if both are protons and F3 if one is proton and the other is neutron. Then
