The basic goals of this program remain the experimental determination of fundamental properties of atoms and molecules, and of molecular clusters, and their use as benchmarks in comparison with computed properties based on theoretical models. In particular we are continuing our measurements of polarizabilities of highly polar molecules and their polymers, and of a number of important atomic elements, particularly several with high-Z. In a parallel program we are performing electron-scattering experiments on these systems. For the scattering program an entirely new apparatus has been designed and constructed. Preliminary scattering measurements have been made, and a summary of these and of problems encountered in this work is presented. Our recently completed alkali-halide dimer polarizability measurements have led to a combined theoretical-experimental determination of alkali halide monomer polarizabilities: the first available values for these important parameters. Our absolute electron-atomic lithium cross section has enabled us to calibrate earlier measurements of electron-Li/sub 2/ cross sections.
