Abstract:

Using high resolution semiconductor detectors, a study was made of the large K-ionization cross sections of atoms over a wide range of atomic numbers Z 29 to Z 83 and of incident electron energies E 150 MeV to 900 MeV. For the higher Z elements Z 60 the L X-ray cross sections were also measured over the incident electron energy range. Ratios of the relative intensities of various distinct lines were determined and compared to recent low energy work. The results of the K-ionization experiment are compared to the recent relativistic calculations of H. Kolbenstvedt. A search for nuclear gamma-rays produced by high energy electron scattering was also undertaken in this work. No nuclear gamma-ray lines were detected. The null results were explained by recent theoretical calculations. Author
