Textbooks

Krane, K.S. Introductory Nuclear Physics (Wiley, 1988), Chapter 11 (Nuclear Reactions) and Chapter 12 (Neutron Physics). The standard upper-division treatment, with clear derivations of the Breit-Wigner formula and its applications. Chapters 11.7–11.9 cover the compound nucleus model and resonances at the level assumed in this chapter.
Blatt, J.M. and Weisskopf, V.F. Theoretical Nuclear Physics (Wiley, 1952; reprinted Dover, 1991). The classic graduate-level reference. Chapter VIII derives the Breit-Wigner formula rigorously from the R-matrix formalism. Chapter IX covers the statistical model. Dense but authoritative.
Satchler, G.R. Introduction to Nuclear Reactions, 2nd ed. (Oxford University Press, 1990). An excellent graduate-level treatment of reaction theory, including compound nuclear reactions (Chapter 4), the optical model (Chapter 3), and direct reactions (Chapter 5). More modern than Blatt-Weisskopf, with better notation.

Feshbach, H. Theoretical Nuclear Physics: Nuclear Reactions (Wiley, 1992). The definitive theoretical treatment by one of the architects of the optical model and the Hauser-Feshbach model. Chapters 3–5 cover the compound nucleus in full generality. For serious graduate students and researchers.
Thompson, I.J. and Nunes, F.M. Nuclear Reactions for Astrophysics (Cambridge University Press, 2009). Specifically oriented toward nuclear astrophysics applications. Covers compound nuclear reactions, level densities, and Hauser-Feshbach calculations as inputs to nucleosynthesis models.
Iliadis, C. Nuclear Physics of Stars, 2nd ed. (Wiley-VCH, 2015). The best modern textbook on nuclear astrophysics. Chapters 2 (nuclear reactions) and 4 (resonances) cover the compound nucleus model with explicit astrophysical applications. Chapter 5 treats the $s$-process and $r$-process in detail.

The recommended evaluated nuclear data library for the United States, containing complete cross sections, resonance parameters, and angular distributions for hundreds of isotopes.
JEFF-3.3 — The Joint Evaluated Fission and Fusion File, maintained by the NEA Data Bank (OECD). The European counterpart to ENDF/B.
JENDL-5 — The Japanese Evaluated Nuclear Data Library. Released 2021 by JAEA.
TALYS — Koning, A.J., Hilaire, S., and Duijvestijn, M.C. A Hauser-Feshbach model code for calculating nuclear reaction cross sections. Freely available at https://tendl.web.psi.ch/tendl_2021/talys.html. Includes built-in level density models, optical model potentials, and gamma-ray strength functions.

Bohr, N. "Neutron Capture and Nuclear Constitution," Nature 137, 344–348 (1936). The original paper introducing the compound nucleus model. Short, elegant, and remarkably clear. Bohr's billiard-ball analogy appears here.
Breit, G. and Wigner, E. "Capture of Slow Neutrons," Physical Review 49, 519–531 (1936). The derivation of the Breit-Wigner resonance formula. A landmark of theoretical nuclear physics, published the same year as Bohr's compound nucleus paper.
Hauser, W. and Feshbach, H. "The Inelastic Scattering of Neutrons," Physical Review 87, 366–373 (1952). The paper that introduced the statistical model for compound nuclear reactions. The Hauser-Feshbach model remains the standard computational tool for nuclear reaction cross sections.
Bethe, H.A. "An Attempt to Calculate the Number of Energy Levels of a Heavy Nucleus," Physical Review 50, 332–341 (1936). The Fermi gas level density formula derived here. Another 1936 paper — a remarkable year for nuclear theory.

Ghoshal, S.N. "An Experimental Verification of the Theory of Compound Nucleus," Physical Review 80, 939–942 (1950). The classic test of the Bohr independence hypothesis using ${}^{64}$Zn$^*$ formed by p + ${}^{63}$Cu and $\alpha$ + ${}^{60}$Ni.
Porter, C.E. and Thomas, R.G. "Fluctuations of Nuclear Reaction Widths," Physical Review 104, 483–491 (1956). The derivation of the Porter-Thomas distribution for reduced neutron widths. A key paper connecting nuclear physics to random matrix theory.

Burbidge, E.M., Burbidge, G.R., Fowler, W.A., and Hoyle, F. "Synthesis of the Elements in Stars," Reviews of Modern Physics 29, 547–650 (1957). The famous B$^2$FH paper — the founding document of nuclear astrophysics. Sections on the $s$-process and $r$-process remain essential reading.
Kasen, D., Metzger, B., Barnes, J., Quataert, E., and Ramirez-Ruiz, E. "Origin of the Heavy Elements in Binary Neutron-Star Mergers from a Gravitational-Wave Event," Nature 551, 80–84 (2017). One of the key papers interpreting the kilonova from GW170817 in terms of $r$-process nucleosynthesis.

Weidenmuller, H.A. and Mitchell, G.E. "Random Matrices and Chaos in Nuclear Physics: Nuclear Reactions," Reviews of Modern Physics 81, 539–589 (2009). A comprehensive review connecting random matrix theory to compound nuclear reactions, resonance statistics, and Ericson fluctuations.
Rauscher, T. and Thielemann, F.-K. "Astrophysical Reaction Rates From Statistical Model Calculations," Atomic Data and Nuclear Data Tables 75, 1–351 (2000). A large-scale Hauser-Feshbach calculation providing reaction rates for thousands of nuclei relevant to astrophysics.
