The Nuclear Physics group's research is in experimental Intermediate Energy Nuclear Physics. This work is based on experiments carried out at the Thomas Jefferson National Accelerator Facility, a national particle accelerator laboratory in Newport News, VA, and focuses on studies of very light nuclei (few-nucleon systems), typically hydrogen and helium isotopes, but it also includes studies on some very heavy nuclei, e.g. lead. The goals of this work is to study properties of the substructure of nucleons and characteristics of nuclear reactions. The group is part of the Jefferson Lab Hall A Collaboration, a larger collaboration that includes nuclear physicists from this country and abroad whose research is based at the CEBAF electron accelerator of Jefferson Lab. Typically an experiment, including all data taking, is done at Jefferson Lab, while planning, preparation, specialized equipment development and testing, and data analysis are done on campus. Several undergraduate and graduate students have participated in this work over the years. The research of this group is funded by the National Science Foundation.

Research Opportunities for Students
A number of positions (hourly or in the form of stipends) are typically available for students who wish to participate in this research. Funding may also be available for qualified students who are able to spend 8-10 weeks during summers at Jefferson Lab. In addition, students of this group have often competed successfully in securing Department of Energy summer fellowships that provide full funding for a 10 week stay at Jefferson Lab, where they assist the CSULA faculty or Jefferson Lab staff in ongoing experimental work. Students interested in joining this group should contact one of the faculty members listed above.
