Electronic Shell

We present a theory for the electronic shell structure of large metallic clusters. Analytical results are given for the dependence of the shell effect on the cluster size and temperature. In particular, we present results for the shell effect in the cohesive energy and ionization potential. A good quantitative agreement with previous numerical calculations and with experiments on Na clusters is obtained.

Contamination Problem

A simple solution to the serious problem of specimen contamination in the electron microscope is presented. This is accomplished by the introduction of clean helium into the vacuum exactly at the specimen position. The local pressure gradient thus established inhibits the migration of hydrocarbon molecules to the specimen surface. The high ionization potential of He permits the use of relatively large volumes of the gas, without interfering with gun stability. The contamination rate is reduced on metal samples by a factor of 10.
