Core level holes which are created in electron emission spectroscopies of atoms and molecules adsorbed or condensed onto metal surfaces induce a screening charge at the surface. The Coulomb interaction between the induced and the hole charge, called the
This report presents the current state-of-the-art of government-developed Data Element Dictionary/Directory (DED/D) systems. DED/D's are software tools used for managing and controlling information and data. Eleven DED/D systems are described, first using

Values are reported for the absolute yields of KVV Auger electrons from beryllium and L 23VV Auger electrons from aluminum excited by 60- to 220-keV proton bombardment. The measurements were made using semi-infinite evaporated samples, and the results were
The report covers the development of a computer simulation program DEPAF (Design and Performance Analysis of Furnaces) for residential fossil-fuel-fired furnaces. DEPAF is based upon an analytical model which accounts for cyclic (on-and-off) operation of
This conference is an important first for the fire research community. In past years there have been meetings at which grantees have described their work but NBS staff have not made presentations. On other occasions a few of the Center's staff have
This report contains extended abstracts of grants and contracts for fire research sponsored by the Center for Fire Research, National Bureau of Standards and descriptions of the internal programs of the Center for Fire Research. It was prepared as a
An evaluation of the fire properties of generic gypsum board products was made in order to obtain a better understanding of the material's reaction to a fire environment. These gypsum board products are typically used in wall and ceiling assemblies
