✦ Synopsis

Sampling techniques have beei used previously to evaluate jacobian determinants that occur in classical mechanicd descriptions of molekulu scattering. These determinants also occur in the quasiclassical approximation.

A new

.technique isdescnbed

which can be psed to evaluate jacobian determinants which occur in either description. This method is expected to be valuable in the study of reactive scattering using the quasiclassical approximation. 1.
