SPIN POLARIZED ELECTRON PHYSICS
- I am interested in fundamental interactions with electrons that involve spin. Electron spin can be thought of just as a spinning top. However, the electron does not have 'size' (it is a point particle) and the magnitude of the spin can only have only have one value. It is the spin of the electron that gives rise to its magnetic moment.
- In our laboratory (BHS105) I am investigating electron collisions with atomic and molecular targets. These types of experiments shed light on unique spin coupled interactions in the target. I have a particular interest in electron collisions with chiral (handed) molecules. Results from these types of studies can provide information on the origins of the chiral purity observed in nature.
- Our laboratory is presently collaborating with Prof. T.J. Gay from our sister institution, UN-Lincoln, making precision electron spin measurements. The apparatus, shown schematically below, is a wonderful venue for undergraduate students to work with Ultra-High Vacuum technology, Gallium-Arsenide spin sources, optical polarimetry, and Mott electron polarimetry.
