IAEA consultants' meeting on electron-impact excitation cross section data for helium. Summary report

摘要

Brief proceedings and a summary of the conclusions of the IAEA Consultants' Meeting on ''Electron-Impact Excitation Cross Section Data for Helium'', held on 20-21 November 1995, in the IAEA Headquarters in Vienna, Austria, are provided. The main emphasis in the database analysis is given to the transitions between the states with principal quantum numbers n = 2-4. The most important gaps in the existing database for these transitions have been identified, as well as the recently developed theoretical methods which can generate highly accurate cross sections. A course of action has been suggested for completing the electron-impact excitation database for helium in a timeframe conformal with the needs of present fusion energy research.
