Measurements of the Structure of the Nucleon

The Abilene Christian University Nuclear Physics Research Group has a long history of studying the structure of the nucleon. Our research has focused on measurements that will improve our understanding of the anti-quark and spin structure of the proton. More recently we have also joined an effort to improve our understanding of the fission process of heavy nuclei. All of these measurements study the charged particles that are produced by a nucleon beam. The physics goals and current status of the PHENIX, SeaQuest, and NIFFTE collaborations will be reviewed.
