Nuclei, forces, and collective structure

Connect nuclear binding and effective forces to shell structure, collective motion, decay selection rules, and evidence from nuclear observables.

  1. 01

    Nuclear sizes and charge distributions

    Infer a charge radius from a normalized form factor while separating sharp-sphere, charge, and matter radii.

    30 min
  2. 02

    Binding energy and the semiempirical mass formula

    Calculate binding and separation energies with consistent mass conventions, then interpret a fitted liquid-drop approximation.

    30 min
  3. 03

    Nucleon–nucleon scattering and the deuteron

    Connect low-energy phase shifts and shallow bound-state tails while retaining spin and tensor-channel distinctions.

    30 min
  4. 04

    Isospin and charge symmetry

    Organize proton-neutron states by approximate internal symmetry without identifying it with spatial spin or exact mass degeneracy.

    30 min
  5. 05

    Nuclear shell model and magic numbers

    Count fermionic orbital capacities and interpret shell closures without confusing a mean field with the full nuclear interaction.

    30 min
  6. 06

    Spin-orbit force and shell ordering

    Derive the sign, magnitude, and degeneracy balance of a nuclear spin-orbit doublet in a declared effective Hamiltonian.

    30 min
  7. 07

    Collective nuclear rotations and vibrations

    Distinguish rotational bands of a deformed nucleus from quantized small-amplitude shape vibrations using conditional spectral patterns.

    30 min
  8. 08

    Nuclear pairing and odd-even masses

    Use explicit mass-difference conventions to diagnose pairing while distinguishing empirical staggering from a model gap.

    30 min
  9. 09

    Electromagnetic nuclear transition strengths

    Separate reduced matrix elements, angular-momentum factors, and photon phase space when comparing nuclear transitions.

    30 min
  10. 10

    Ab-initio nuclear methods and truncation errors

    Connect a specified nuclear Hamiltonian to finite-space calculations, consistent operators, and a transparent uncertainty budget.
