: It is one of the few texts that thoroughly explores the analytic properties of scattering amplitudes, which are crucial for understanding modern particle physics.
For example, when an electron collides with a hydrogen atom, several "channels" open up: Excitation Channel: Ionization Channel: quantum collision theory joachain pdf
In the quiet, dust-moted corners of the university library, Elias finally found the spine he had been hunting for: Quantum Collision Theory Charles J. Joachain : It is one of the few texts
