When exploring scattering theory in quantum mechanics, several textbooks are recommended, including Sakurai, Merzbacher, and Landau. Landau's book is praised for its insightful introductory chapters, but it is noted to be challenging for beginners due to its mathematical rigor and terse explanations. Sakurai is suggested as a more accessible option for initial study. Additionally, Taylor's book on non-relativistic scattering theory is recommended as a foundational resource. Other notable mentions include Roger G. Newton's "Scattering Theory of Waves and Particles" and N. F. Mott and H. S. W. Massey's "Theory of Atomic Collisions." A solid understanding of complex calculus, contour integration, and related mathematical concepts is emphasized as essential for grasping scattering theory effectively.
