What Does CCA Stand For?

CCA stands for Close Coupling Approximation

Close Coupling Approximation (CCA) is a computational technique used in quantum mechanics and scattering theory to model interactions between particles. By applying this approximation, researchers can accurately describe the dynamics of systems where particles are in close proximity, allowing for precise predictions of their behavior during collisions. CCA is particularly valuable in areas such as atomic and molecular physics, where it facilitates the analysis of quantum states and transition probabilities in complex interactions.
