A. NUCLEAR PHYSICS
1. Bulk properties of nuclei
Nuclear mass, charge, size, binding
energy, spin and magnetic moment. Isobars, isotopes and isotones; mass
spectrometer (Bainbridge).
2. Nuclear structure

nuclear stability and nuclear binding, the liquid drop model (descriptive) and
the Bethe-Weizsacker mass formula, application to stability considerations,
extremesingle particle shell model (qualitative discussion with emphasis on
phenomenology with examples).
3. Unstable nuclei

alpha particles. Geiger-Nuttal law.
(b) Beta
decay : nature of beta ray spectra, the neutrino, energy levels and decay
schemes, positron emission and electron capture, selection rules, beta
absorption and range of beta particles, Kurie plot.
(c) Gamma decay : gamma ray spectra and nuclear energy levels,
isomeric states. Gamma absorption in matter, photoelectric process, Compton
scattering, pair production (qualitative).
4. Nuclear fission and fusion
Discovery
and characteristics, fission products and energy release, spontaneous and
induced fission, transuranic elements. Chain reaction and basic principle of nuclear
reactors. Nuclear fusion: energetics in terms of liquid drop model.
B. SOLID STATE PHYSICS
