Abstract : The purpose of the program was to investigate the ionization potentials of small particles as a function of particle size. Three types of particles were prepared for various aspects of this program: (1) cesium antimonide particles grown in ammonia, (2) polydispersed aluminum particles grown in a carrier gas to minimize contamination, and (3) monodispersed sulfur particles grown in water. The objectives of producing each type of particle were to provide particles of (1) low work function, (2) high chemical purity without appreciable surface contamination, and (3) single size, respectively. In order to size particles, the technique using monochromatic X rays was tried with graphite particles. A sensitive method for the detection of heavy charged particles in a carrier gas was investigated and is being applied to the measurement of electron extraction energies of aluminum particles.
