Positron annihilation spectroscopy of Earth materials: A combined materials characterization approach
Principal Investigator: Heather Watson, John D. MacArthur Assistant Professor of Physics and Astronomy; Senior Personnel: Michael Vineyard, Frank and Marie Louise Bailey Professor of Physics and Astronomy

This project will further understanding of the atomic-scale physical properties of several relevant Earth materials through the development of a very high resolution materials characterization technique called positron annihilation spectroscopy. The benefit of this technique is that it allows for direct investigation of crystalline solids at an atomic level, which is not routinely done with the conventional methods used in the geosciences. The undertaking will involve interdisciplinary collaborations between nuclear physicists and experts in the area of materials characterization and geoscience. The project will also support two women faculty, undergraduate curriculum development, and advanced student research at Union.
