The utility of a l/sub z/-conserving approximation, resulting from only energy sudden approximation to the exact space fixed coupled equations, is investigated for atom--diatom scattering. It is shown that the expressions for various transitions probabilities and differential cross sections may be obtained after evaluating relatively small number of l/sub z/-conserving S-matrix elements. Numerical comparisons with IOS and CC results are given for Ar--N/sub 2/ and Ar--Tlf for a set of previously well studied parameters.
