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.
