Those volumes acquire forty-four chosen papers from the medical contributions awarded on the 3rd eu Workshop on Quantum structures in Chemistry and Physics, held in Granada (Spain), April 19–22, 1998. Ninety-nine scientists from Bulgaria, Columbia, Cuba, Denmark, Finland, France, Germany, Hungary, Israel, Italy, Mexico, Netherlands, Norway, Poland, Russia, Slovakia, Spain, Sweden, United Ki- dom, Uruguay and Venezuela attended the workshop, discussing the cutting-edge, new developments, and destiny evolution of the equipment and purposes.

This rate of decrease with increasing exposure is approximately the same for an ion-bombarded surface which has been well annealed as for one which has received a small anneal. However, the diffraction patterns from the gas-lattice structures on the surface with the small anneal are much more intense than those from the gas-lattice structures on the well-annealed surface because of the different defect densities in the two cases. If the extinction of the pattern from nickel were caused by the presence of the gas-lattice structures, one should expect a greater rate of extinction for the surface having a small anneal.
Metals. I n the interactions of gases, and particularly oxygen, with metal surfaces, one or more of the above three processes may be observed in order of increasing exposures (pressure x time). I n the initial process of adsorption, the gas, if diatomic, may remain on the surface in the form of (1) one or more layers in an amorphous molecular form, (2) a monolayer or less in which dissociated atoms occupy a two-dimensional lattice with the same atomic arrangement and spacing as those of the adsorbate or (3) with some larger spacing which is a simple multiple of this spacing.
