| 10 | Assignment Questions
Semester – III (Session: 2023–25)
Paper: CC–13 (Nuclear and Particle Physics)
Q.1. Explain the concept of nuclear reaction cross-section (σ). Discuss its physical significance and units. Also describe low-energy neutron–proton (n–p) scattering and explain how scattering cross-section provides information about nuclear forces.
Q.2. Discuss the Single-Particle Shell Model of the nucleus. Explain the origin and significance of magic numbers. Give experimental evidence supporting the existence of magic numbers and compare the Shell Model with the Liquid Drop Model.
Paper: CC–10 (Atomic and Molecular Physics)
Assignment Questions
Q.1. Derive the expression for the vibrational energy levels of a polyatomic molecule. Discuss the different modes of vibration and their significance in molecular spectroscopy.
Q.2. Explain the Quantum Theory of Raman Effect. Discuss the origin of Stokes and Anti-Stokes lines with suitable energy level diagrams.
Q.3. Draw the schematic energy-level diagram of a three-level laser system. Derive the conditions for population inversion and provide the mathematical analysis of laser action. | 230 |
