Abstract:

The DNA Uranium Oxides LWIR Review Committee considered the effectiveness of field measurements of the LWIR from uranium oxides produced by hypothetical controlled releases of uranium vapor from rockets in the thermosphere. Collated here is the writers work supporting the committee on atomic and molecular collision aspects of such releases. Included is an essential auxiliary study to a understand, in terms of atomic and molecular parameters, coefficients for Ba diffusion along the magnetic field as measured and predicted for Ba-release events and b apply that limited understanding to U-release studies. For particles colliding with neutral atmospheric species, several interaction potentials are used to compute velocity-dependent momentum- transfer cross sections, stopping power and range versus energy, and diffusion coefficients. The momentum-transfer cross sections are also compared with cross sections for certain uranium oxide reactions specially atom-transfer reactions.
