With the aid of a new method of the short-collision-time expansion, a quasiclassical formula for the differential scattering cross section of a slow neutron is derived along the line of reasoning of the well-defined quasiclassical prescription proposed in a previous paper. The formula satisfies the condition of detailed balance and a sum rule, and has the correct limit of weak binding of the target system. The scattering from a system of molecules is treated in the present formalism, and a systematic method for the correction to the Krieger-Nelkin approximation is obtained. The effectiveness of this correction method is demonstrated in anumerical calculation for HCl gas.
