Dr. Khakoo's Research

Dr. Khakoo focuses his research efforts on experimental inquiries into atomic physics -- specifically, on electron scattering from fundamental targets.

The goal of this research is to provide experimental electron-gas scattering data in the form of cross-sections, cross-section ratios, and coherence and correlation parameters as fundamental tests of current electron scattering models. As well as spin polar electron polarimetry; gas dynamics of molecular beams; and atomic and molecular sources from discharge media. This information is very useful for plasma processing applications, astrophysical modeling applications, lighting industry applications, and Tokamak magnetic confinement fusion research. With special interests in fundamental targets such as H, He, rare gases, metallic vapors, and H2, N2, O2, CO, and CO2.
