A series of lectures will be given on the following topics: Part I: Overview of the Nuclear Landscape – trends in masses, separation energies, – nuclear excitation and level schemes, level densities – regions of applicability of the shell model, collective models, and deformation. Part II: The Nuclear Mean Field – nucleonnucleon interaction and potentials, – development of the mean field and effective interactions, – HartreeFock equations their solutions, wave functions, and singleparticle energies, – phenomenological mean fields, WoodSaxon and harmonic oscillator. Part III: The Meanfield Shell Model – oneparticle and onehole nuclei – twoparticle and twohole nuclei – particlehole states – twobody interactions – the surface delta interaction – configuration mixing – multiparticle states – np states and isospin formalism Part IV: Pairing Correlations – pairing interactions – seniority scheme – BCS model and quasiparticles – BCS equations, pairing gap and pairing energies – Lipkin and LipkinNogami models – pairing vibrations Part V: Deformed Mean Fields – HFB theory and Bogoliubov transformations – deformed shell model and the Nilsson scheme
– –

Part VI: Collective Hamiltonians – the BohrMottelson Model – liquid drop and its quantization, – BohrMottelson Hamiltonian and solutions – surface vibrational models – largeamplitude oscillations – deformed rotational nuclei – beta and gamma degrees of freedom – shape transitions Part VII: Algebraic Methods in Structure – group theory techniques and chain reductions – Elliot SU(3) model – boson expansion methods – Interacting Boson Model – projection of shell model and collective states – IBM solutions and transitions
