Electron-Impact Total Ionization Cross-Sections of the Chlorofluoromethanes

January 1, 2003
Author(s)
Karl K. Irikura, M A. Ali, Yong Sik Kim
Electron-impact total ionization cross sections for CCl 3F (Freon 11), CCl 2F 2 (Freon 12), CClF 3 (Freon 13), CHCl 2F (Freon 21), CHClF 2 (Freon 22), and CH 2ClF (Freon 31) are calculated using the Binary-Encounter-Bethe (BEB) theoretical model. The BEB

Enterprise Access Control Frameworks Using RBAC and XML Technologies

January 1, 2003
Author(s)
Ramaswamy Chandramouli
In this chapter, we show that we can develop an Enterprise Access Control Framework using Role-based Access Control (RBAC) and Extensible Markup Language (XML) technologies. In the first section, we outline the general requirements for the Enterprise

Estimation of Neutron Mean Wavelength From Rocking Curve Data

January 1, 2003
Author(s)
Kevin J. Coakley, Z Chowdhuri, W M. Snow, J M. Richardson, Maynard S. Dewey
At NIST, an in-beam neutron lifetime experiment is underway. In part of the experiment, a neutron detector is calibrated. The accuracy of the detector calibration depends, in part, on how accurately the mean wavelength of a neutron beam can be estimated
