Abstract :
The process of stimulated cooperative Raman-type scattering of correlated photon pairs is discussed as a physical mechanism for entangling atomic subsystems. The process of coherent forward scattering of light in a polarized atomic gas with an arbitrary angular momentum is also discussed in context of quantum entangling process. The developed general formalism is applied to test the applicability of the spin 1/2 approximation for modelling the quantum non-demolishing measurement in an ensemble of atoms with a higher angular momentum.
