Subatomic physics is the study of the constituents of matter on the scale of the atomic nucleus, and smaller, and their interactions. Our primary experimental efforts are centered on nuclear structure, nuclear astrophysics, and searches for physics beyond the Standard Model using Canada's world-leading radioactive beam facilities, ISAC and ISAC-II, located in Vancouver at TRIUMF. Major experimental facilities at TRIUMF operated by us include the TIGRESS and 8pi gamma-ray spectrometers, and we are currently developing the DESCANT array of neutron detectors. Our research also includes experimental work performed at world-leading laboratories worldwide, including the Maier-Leibnitz Laboratory at Munich, the Van de Graaff Accelerator facility in Lexington, Kentucky, and Argonne National Laboratory near Chicago. Our theoretical efforts concentrate on nuclear forces, the structure of nuclei and the synthesis of heavy elements, the physics of superfluidity, the structure of neutron stars, and several related topics.
