4. Assuming square well type of nuclear potential, give
the theory of the deutron problem. Obtain a relation
between the depth and width of the well and
deutron binding energy.
Discuss the excited states of deutron.
Write the properties of deutron.
5. Discuss the neutron-proton scattering at low
energy. Show how the assumption of spindependence
of nuclear force can explain the
experimental results.
Explain the method of partial wave analysis for n-p
scattering and determine the phase shift.
6. Describe Bohr's compound nucleus formation
hypothesis for nuclear reactions.
Explain the continuum states of the compound
nucleus.
Discuss the decay rates of the compound nucleus.
7. Explain the interaction of neutron with matter.
Find the energy loss after collision and average
energy after collision.
Discuss about thermal neutrons. Also, explain
energy distribution of thermal neutrons and flux
distribution for thermal neutrons.
Determine the critical size of the nuclear reactor.
8. Explain the classification of elementary particles.
Discuss the conservation of leptons and baryons.
Write a note on quarks.
