{The negative ionization of sputtered carbon atoms}."
Applied Surface Science. 144-145 (1999): 208-211.
AbstractThe formation and survival probability of negative carbon ions sputtered from a graphite sample was determined. The energy distribution of Cy ions was measured experimentally and the energy distribution of all sputtered carbon atoms was obtained from a computer simulation with the program TRIM.SP. From the two distributions, we obtained the probability that a carbon atom would capture an electron from the graphite and subsequently survive as it moves away from the surface. Ż. The results show two different situations. At low energy below 25 eV , the sputtered particles are all negatively ionized when the affinity level crosses the graphite Fermi level and afterwards, the population decay follows a semi-classical rate equation. Ż.At higher energy above 25 eV , a velocity-dependent fraction reaches the crossing distance as neutral atoms

University Library of Munich, Germany, 1999.
AbstractThis is the second interim report of the research project "Information Society, Work and the Generation of New Forms of Social Exclusion" (SOWING). It is based on a firm survey conducted in the eight regions participating in the research project — Flanders (Belgium), Lazio (Italy), Niederösterreich (Austria), Portugal, the Republic of Ireland, the Stuttgart area (Germany), the Tampere region (Finland) and the West London area (U.K.). The aim of this report is to present a broad overview of the collected data. In general, only simple statistical methods have been applied. The report focuses on a regional comparison; however, the data have also been analysed by firm size, measured by quantity of staff, and industrial sector. It should be seen as a first step in the data analysis; it may also give some hints for a more strategic analysis of the survey data.
