Abstract
An approximate procedure for carrying out absorption corrections is presented. It is simpler to apply than the usual procedure, in that the impact-parameter integrals are replaced by simple factors. One can perform the absorption corrections directly on the helicity amplitudes, without performing a partial-wave expansion. The procedure allows one to reproduce approximately all of the results of the usual method, including the polarizations of the produced particles, with only the parameters present in the usual approach.
