Aerosol Methods in Cluster and Small Particle Research

Abstract

For basic investigations on small particles or clusters a number of experiments use Suspension of the finely dispersed material in a gas. Examples of such experiments that have led or may lead to discovery of interesting properties of small particles are reviewed. Most of the review deals with aerosol photoemission (APE), as well as its application in measurement of gas adsorption to small particles. A method of sensitive detection of size changes of aerosol particles in the sub-monolayer range together with an application is reviewed as a further method of adsorption measurement. The newest result in X-ray absorption spectroscopy on aerosol particles is shown. Finally, the possibility of measuring aerosol coagulation with the aim of estimating forces between particles is explained and surprising results obtained with this method are mentioned.
