OK, let's suppose that all you have said is correct. But! how does an atom recoil while emitting circularly (or spherically -older terminology-) polarized photon in the existence of spherical symmetry? Do the textbooks tell wrong?
and also, the atomic recoil in Raman-Nath approximation is...
but i am sure that the COM changes if atom emits spherically polarized photon (i learned this from many textbooks). Cause there is a very well-known Raman-Nath approximation which supplies the neglect of the center of mass change for sigma polarizations (spherically polarized photon emission)...
Hi,
i have a question about the center of mass change during photon emission in terms of the polarization of the emitted photon.
first, a few facts are as follows:
i) selection rule: if delta m=0, that means p (atomic recoil) = p (photon) in magnitude. This is of pi transition and...
