Intro to Quantum Mechanics II
The scattering cross-section is a measure of the probability of scattering events occurring between particles, often expressed in terms of an effective area that quantifies how likely an incoming particle will interact with a target particle. This concept is crucial for understanding interactions at the quantum level, particularly when discussing atomic transitions and the influence of phase shifts on scattering processes. The larger the cross-section, the higher the likelihood that scattering will occur.
congrats on reading the definition of scattering cross-section. now let's actually learn it.
