Perform Quantum Chemistry Calculations on Element 104 Using Existing Computer Programs: Foreign Trip Report, June 1, 1988-May 10, 1989.

摘要

Electron ionization energies and parameters for the atomic radii of elements 104 and 105 are discussed. Values for these properties have not been proposed before. The results are expected to provide part of the basis for the calculation of certain chemical properties of elements 104 and 105. Chemical properties of elements 104 and 105 are difficult to determine experimentally because of the short half-lives and low production rates of these elements. A fully numerical method for the solution of the Schrodinger equation of quantum mechanics is discussed. Fully numerical methods are capable of yielding more accurate results than the method that was used to obtain the ionization energies mentioned above. Compared to other fully numerical methods, the method discussed here requires less computation time and it does not have the mathematical singularities that occur in other such methods. Energy research and development projects at the Gesamthochschule Kassel, Federal Republic of Germany are summarized. These projects involve consultation, wind and solar energy production, storage and distribution, hydroelectricity production, the production of biogas, the design of fuel cells, technology transfer, and the political aspects of energy production and distribution. 12 refs.
