Kinds of free-free transition :

• bremsstrahlung (3 kinds, 13 facts) (deceleration radiation, free-free transition) - Radiation emitted or absorbed when a free electron is accelerated in the field of an atomic nucleus but remains in a hyperbolic orbit without being captured. Since bremsstrahlung is not quantized, photons of any wavelength can be emitted or absorbed. (Also called a free-free transition because the electron is free both before and after the transition.), Electromagnetic radiation given out by electrons interacting with the ions in an ionized gas.
• inverse bremsstrahlung (4 facts) - Absorption of a photon by an electron in the field of a nucleus.
