The RQCS code is designed to supply multigroup constants for thermal neutron reactors. It deals with a flexible input format of differential nuclear data which is similar to but somewhat simpler than that applied in ENDF/B library. There are thirteen types of group averaged cross sections as output constants, including elastic transfer cross sections.Each element of the high order transfer matrices of elastic scattering results from a double integral, its inner integral is given by R_ι(E,μ_1,μ_2)=integral from μ_1 to μ_2 P_ι(μ)P(μ,E)dμ. It is the oscillation property of Legendre function in the integrand that makes the calculation of elastic matrices the most timeconsnmming work in the whole calculation, particularly when the order 1 gets higher (1=8 for example). In the early stage of our work, we studied the method proposed in MIGROS-3 (KFK-2388), but we found the calculation speed of this method was too low to make the method practicable for 1=8 when using a medium computer, therefore we propose a new method, in which the inner integral may be obtained by interpolation and simple algebraic operation. The calculation speed of this method is faster than that of the KFK method.
