Text: SUBATOMIC PHYSICS, 3rd Edition, by Henley and Garcia (World Scientific, 2007, 2010). Errata for Ch. 6, and errata for Ch. 11.  [I have located a free pdf version of the text, here.]  And here is a very compact introduction to the theory of scattering. A short course in nuclear physics. Highly recommended supplementary text: PARTICLES AND NUCLEI, 7th edition, by Povh, Rith, Scholz, Zetsche and Rodejohann (Springer, 2015). The only reason I don't use this as the primary text is that it has no homework problems.

Answers to in-class quizzes:  (1) The Feynman diagram is for pair creation.  Since the photon is massless and the electron and positron have a mass of 0.5 MeV, total energy and momentum can't be conserved unless another massive object (the nucleus of a heavy atom) is also involved in the initial state of the process. (2) Clearly a system made of a particle and an antiparticle is not going to be stable. What's astonishing is that all strongly-interacting composite particles can be put into two groups, baryons and mesons, and it turns out no meson is stable, and only one baryon seems to be stable, the proton.  (3) Typical average lifetimes: strong processes, 10⁻²³ sec; electromagnetic processes, 10⁻¹⁷ sec; weak processes, 10⁻¹⁰ sec, as you would expect. (4) The neutral D decay involves a W+ boson, the gauge boson of the weak force.  (5) Isospin obeys the same rules as angular momentum, so isospin T results in a 2T+1 multiplet. Since 2T+1 = 5, T = 2.  (6) The Poynting Vector is a cross product of a polar vector E and an axial vector B.  So it transforms like a polar vector. PS = -SP. (7) Photons emitted by pointlike fundamental particles are virtual.  (8) A negative pion decaying to a muon and an anti-muon-neutrino is of course a semi-leptonic process.  (9) ALL of the statements about the weak interaction are correct.  (10) The original quark model (1961) used only 3 quarks, u, d and s.  (11) The spectra of ⁶⁴Zn and ¹²²Te exhibit the classic pattern of vibrational nuclei... a one phonon (λ = 2) state and then a triplet indicating excitation of two coupled λ = 2 phonons. If you missed this straightforward question, take it as a warning that you are not now keeping up in the class or comprehending even very basic material.  (12) If a nucleus has a half-life of one day, and at some point a sample contains 10,000 such nuclei, one day later there will be 5,000.  (13) 48% comes from diagnostic X-radiation, and 37% from radioactive gases emitted by subsequent decays of naturally-occurring U and Th in dirt and rocks.  (14) Fission releases a kinetic energy of about 1 MeV per nucleon, 200 MeV total.  (15) The first physicist to suggest that the chemical elements were forged by nuclear processes in the cores of stars was Sir Arthur Eddington.  When other physicists expressed skepticism, Sir Arthur would always reply, "Then why don't you go find a hotter place?"  (16) The first physicist to realize that the universe must have started out in a very hot, extremely dense state (and to estimate a value of the Hubble constant before Edwin Hubble even discovered the expansion of the universe observationally) was Georges Lemaître.  (17) Only about 4% of our universe consists of ordinary matter--- electrons, protons, neutrons (in nuclei), neutrinos and photons.  (18) It's pretty much universally agreed now that the idea of supersymmetry is incorrect.
