The emission of a photon by an isolated atom is a recoil process in which momentum is

Question:

The emission of a photon by an isolated atom is a recoil process in which momentum is conserved. Thus Eq. (39.5) should include a recoil kinetic energy Kr for the atom. Why is this energy negligible in that equation?

Eq.39.5

Speed of light in vacuum Final energy of atom after transition Energy of emitted photon = E – E λ. - Initial energy o
