https://doi.org/10.1007/978-0-387-09488-5 upon transition of electrons in the levels of the valence band to vacancies in inner core levels. The density of states in the band is dependent on the particular atom and upon the lattice structure. To carry these ideas over to alloys is not, however, self-evident, especially if the alloy has a di

Linda Patia Spear,Frank M. Scalzoe discussed and data on low atomic number elements are given. For polychromatic X-ray spectra, effective wavelengths and excitation efficiencies are measured as a function of atomic number. A new dual-target X-ray tube is shown to be an effective answer to the problem of covering a broad range of el

Mariana Gonzalez Insua,Edurne Battistadied and appropriate methods developed, these are added to the list of control procedures. Each of these materials presents different types of problems to the analyst, and must be investigated with this in mind. One problem common to almost all nonmetallics is the mineralogical differences and origi

Xiaoming Huo,Cheng Huang,Xuelei Sherry Nipproximation used by Parratt for argon atoms in which the .-excited terms of argon are compared to the optical terms of potassium. It is pointed out that this approximation is very poor in the range of small atomic numbers, and this approximation also predicts the wrong number of X-ray term values.

Michelle Cheatham,Catia Pesquitacc, has a cell efficiency of 3.08 as defined by the ratio of path length to volume. The second cell, having a path length of 9 mm and a volume of 0.045 cc, has a cell efficiency of 20. This cell is designed for use with a beam condensing system.
