Module 01 advanced
Reaction dynamics and nuclear transformations
Analyze decay and reaction observables through conservation laws, barrier penetration, resonance theory, and experimentally constrained reaction models.
- 01
Reaction Q-values and threshold energies
Track mass conventions and derive the difference between reaction energetics and a fixed-target beam threshold.
34 min - 02
Two-body nuclear reaction kinematics
Transform relative motion into laboratory observables without assigning a dynamical angular distribution.
34 min - 03
Alpha decay and Gamow penetration
Separate energy release, barrier tunneling, cluster formation, and the measured partial decay rate.
34 min - 04
Beta-decay spectra and Fermi theory
Derive the allowed spectral shape from lepton phase space and state the limits of selection rules and endpoint approximations.
34 min - 05
Gamma-decay multipolarity and lifetimes
Use spin and parity to identify photon multipoles while distinguishing radiative strength from a total level lifetime.
34 min - 06
Compound nuclei and Breit–Wigner resonances
Relate formation, partial decay widths, spin averaging, and inverse-channel reciprocity for an isolated resonance.
34 min - 07
Direct reactions and optical potentials
Interpret complex elastic-channel potentials and partial-wave absorption without confusing flux loss with particle destruction.
34 min - 08
Neutron cross sections and resonance absorption
Connect microscopic areas to beam attenuation, spectrum-weighted rates, and the conditional scope of a 1/v law.
34 min - 09
Nuclear fission barriers and fragment distributions
Separate deformation stability, tunneling, energy partition, and the normalization of measured fragment yields.
34 min - 10
Fusion barriers and astrophysical S-factors
Separate kinematic Q-values, Coulomb penetration, intrinsic nuclear strength, and thermal reaction averaging.
