Book Description
The basic goals of this program concern the experimental determination of properties of atoms and simple molecules that are important in a wide range of energy-related processes. In particular we have initiated measurements of polarizabilities of highly polar molecules and dimers, and of a number of atoms distributed through the periodic table, and, of the scattering of low energy electrons by highly polar molecules. For this latter series of measurements an entirely new apparatus has been designed and its external components have been completed. A new electron optics assembly has also been designed and is currently under construction. Details of all these projects are presented; analysis and data of the polarizability measurements are also given.

Book Description
A program was initiated to measure the electric dipole polarizabilities, higher energy moments and cross sections for the scattering of low energy electrons by alkali halide molecules, their dimers and larger clusters. Preparatory work is also being carried out to perform similar measurements on the important atomic species, N, O, C and S. This report presents some preliminary data of the measurements of the polarizabilities of (CsCl)2, (RbCl)2 and (KCl)2. A description is contained of a new scattering apparatus now under construction that will enable scattering experiments with high energy (

Book Description
The basic goals of this program concern the experimental determination of properties of atoms and molecules and molecular clusters that are important in a wide range of energy-related processes, in particular, measurements of polarizabilities of highly polar molecules and their polymers, and of a number of important atomic elements distributed through the periodic table, as well as of the scattering of low-energy electrons by these same systems. The most significant scientific accomplishment of the program during the past year has been the completion of measurements of the dc electric dipole polarizabilities of a number of alkali halide dimers ((KCl)2, (RbCl)2, (CsCl)2, (KF)2, and (CsF)2). An experiment was completed to measure the total cross sections for the scattering of low-energy electrons by atomic lithium, a very significant experimental test of a relatively simple, many-body system, which is amenable to elaborate computational determination.
