Will anyone give me an explanation helping me understanding it?
Welcome to Physics Forums.
The recoil energy is p2/2m, where p=h/λ is the momentum of a lattice photon and m is the mass of an atom or ion trapped in the lattice.
The recoil energy is the kinetic energy an atom (or ion) would have after emitting a photon, if initially at rest.
Recoil energy E=Mv2/2=p2/(2M)=Ep2/(2Mc2)=([tex]\hbar[/tex]k)2/(2M).
M=mass of something (nucleus, atom, ion, etc), which emits photons.
v=recoil velocity due to emission of photons.
Ep= Energy of the emitted photons.
c=velocity of light in vacuum.
I see, Thanks a lot
