In physics, a few-body system consists of a small number of well-defined structures or point particles. It is usually in-between the two-body and the many-body systems with large N. == Quantum mechanics == In quantum mechanics, examples of few-body systems include light nuclear systems (that is, few-nucleon bound and scattering states), small molecules, light atoms (such as helium in an external electric field), atomic collisions, and quantum dots.
