Abstract
The scattering of slow neutrons from spherical-top molecules of point group is analyzed and discussed, taking into account the rotation-vibration interaction. After the introduction of the general formulation for the partial differential cross section, the Hamiltonian of the spherical-top molecule is discussed, and the contribution of the rotation-vibration interaction is considered in detail. By using group-theoretical methods, the rotational-vibrational wave function, and then the total wave function, are obtained. Finally, explicit extensive expressions for the intermediate scattering function and the partial differential cross section are derived.
