Abstract
Calculations of slow-neutron partial differential scattering cross sections are reported for molecules with linear symmetry in which the quantum-mechanical nature of the rotational levels is taken explicitly into account. The method used is an extension of Griffing's results to nonspherical molecules. The calculations for HF, HCl, N2, and HCN gases are compared to calculations based on the Krieger—Nelikn approximation, and the failure of the latter method to account correctly for rotational-energy transfers is pointed out.Keywords
