It is proposed that the scattering of positrons and                     electrons by atoms and molecules be studied experimentally in                   order to learn more about basic interactions of antimatter with                 matter.  The proposed research includes measurement of total,                   differential, and inelastic scattering of positrons by atoms and                molecules, as well as a search for positron scattering                          resonances.  An important part of the research program is to make               corresponding electron scattering comparison measurements in the                same apparatus using the same technique.  Information will be                   obtained that is of interest in many areas of science and                       technology.  For example, the scattering of positrons by atomic                 and molecular hydrogen is of importance to astrophysicists for                  the interpretation of positron annihilation gamma rays observed                 in solar flares and in the central region of our galaxy.
