Feshbach resonance is a phenomenon in quantum mechanics and atomic physics that occurs when the energy of a colliding particle pair (such as atoms or molecules) becomes equal to the energy of a bound state of those particles. This typically involves the coupling of different scattering channels, leading to a significant modification of the interaction potential between the particles.
