Microwave photon recoil
WebThe recoil temperature is , since the photon's momentum is (here is the wavevector of the light, is the mass of an atom, is the Boltzmann constant and is the Planck constant ). The recoil temperature for the D 2 lines of alkali atoms is typically on the order of 1 μK, and thus lower than the Doppler temperature.
