Chapters 9, 11, 12 Concepts covered that will also be candidates for exam questions

Ionic bonds and different components of energy: ionization E, repulsion E, coulomb attraction E, disassociation E Excited states of molecules, different components of spectra (electron transitions, vibrational, rotational) Selection rules for molecular transitions Spontaneous emission and zero-point vacuum fluctuation field

Radius of nucleus, how to find (R = R 0 A 1/3 ) Binding E of nucleons in a nucleus (2 approximate eqns, not semi-empirical eqn) Radiation types: alpha, beta, gamma Exponential decay law, differences between TAU (τ, mean life) and T1/2 (t ½, half life) Equations for the Q value or E of decay of beta decay, for e+ and e- emission Full description of alpha decay as a QM tunneling 2 conservation laws in nuclear reactions

Cross section – how to calculate and what it implies (probability for interaction to occur) Fission: how it happens, why you need E input to make it happen Nuclear reactor components (k factor, moderator, critical mass, control rods) Fusion: how it happens, why you need E input to make it happen

Why the field is called high energy physics How to use the uncertainty principle to determine the mass of a hypothetical particle that is the carrier of the strong force Leptons, hadrons, fermions, bosons: what these are Standard model: types of elementary particles, families, antiparticles 3 forces (EM, strong, weak), what particles they act on Force carriers (how particles really interact via the exchange of particles that “carry” the force) and virtual particles Weak force, only force to allow generational mixing, only interaction type that allows S violation Conserved quantities in particle interactions, including color (ONLY focused on energy, mass, momentum, charge, lepton number, baryon number, strangeness, color)

Sources of neutrinos, ordered by E of the source 4 categories of Weak interactions (NC, CC: CCQE, CC pion, CC DIS) What is Cerenkov and Scintillation light, how to calculate if a particle will produce Cerenkov light in your detector How do we understand the phenomenon of neutrino oscillation proceeds? – flavor neutrinos of standard model: electron neutrino, muon neutrino, tau neutrino, are all actually representations of a superposition of 3 other neutrino waves that carry different values of mass. Viewing the superposition of the 3 mass waves at any point in space determines if you see or don’t see oscillations, or neutrinos changing flavor

Uncertainty principle in beta decays Radii of nuclei Radioactivity: half-life, decay constant, counting rates, activity, atoms in samples E of particles participating in alpha, beta decays Compare strength of forces, mass of force carrying particles Reactions using cross section, beam and target information Q and total E produced in fusion reactions Range of alpha particles, decay constant/half life in alpha decays

Threshold for photodisintegration E of decay products in beta decay without a neutrino being produced Conservation of quantities in annihilation reactions Identifying forces that allow interactions to proceed, allowed & forbidden interactions under these forces Conserved quantities in particle reactions
