Aaron Couture Aaron Couture is engaged in the experimental study of neutron capture by hook or by crook. Neutron capture is responsible for the production of almost all of the observed elements heavier than iron. Nuclear waste transmutation concepts rely on neutron capture to reduce long-lived radionuclide inventories. Nuclear forenics relies on understanding neutron reaction networks. Where possible, these reactions are measured directly with neutron beam facilities such as LANSCE at Los Alamos. These measurements are complemented by nuclear structure studies on rare isotope beams. This structure information is used to inform and guide nuclear reaction modeling use to predict neutron capture reaction rate predictions off stability. You can also download a poster on his research here: 'Nuclear Science at LANSCE'. |

Peter Kuchment His work is focused in the areas of mathematical physics, medical and homeland security imaging, material science, and enhancement of math education. He had been part of a previous A&M NSF-DHS funded project devoted to prevention of smuggling illicit nuclear materials, where he with collaborators developed techniques of passive detection of presence of such sources, vs high noise background from their gamma-emission. He is currently part of a group lead by Prof. Rogachev that works on neutron detection for the same purpose of prevention of smuggling special nuclear materials. He has written several books including 'The Radon Transform and Medical Imaging' and 'Introduction to Quantum Graphs'. You can also download few posters on his research here: 'Compton Camera Imaging' and 'Source Detection in 2D High Noise Emission Type Problems Using Cone Data'. |

Shea Mosby Neutron-induced reactions play an important role in nuclear technology and national security fields such as stockpile stewardship. Physics quantities of interest include neutron-induced fission cross sections, the fission total kinetic energy release and fission fragment mass distributions. Mosby and his team are developing an instrumentation suite which, when combined with the neutron beams available at the Los Alamos Neutron Science Center, will provide next generation experimental constraints on these quantities. Neutron-induced reactions on short-lived nuclei are an additional area of interest which pose unique challenges and preclude many of the traditional experimental techniques. His work also includes investigating both indirect probes of the reaction mechanics and the feasibility of directly studies of neutron-induced reactions in inverse kinematics.
