Abstract : An analysis is presented which covers the experimental studies of particle-surface interactions completed over the past contract year. The experiments are being carried out both in the laboratory using molecular beam techniques and in the upper atmosphere from satellites. Laboratory investigations have progressed to a point where we are now studying interactions with neutral as well as ion beams on both single and polycrystalline surfaces. Measurements are reported on the sputtering of thin film crystals of copper in beams of noble gases at energies up to 1 keV. Some interesting results on the absorption of a beam of He(+) by aluminum are described. The problems associated with the generation of neutral beams are discussed and preliminary measurements of the sputtering of gold surfaces and neutral argon beams are given. (Author)
