The Nuclear and Particle Physics group at LLNL addresses emerging nuclear security challenges through the application of fundamental research at the frontiers of physics.
Our expertise in accelerator physics, complex data analysis, and detector design and construction—coupled with access to state-of-the-art engineering and high-performance computing facilities—allow us to probe the fundamental interactions of elementary particles and nuclei. Our findings are directly applicable to LLNL’s national security mission, providing insights into and solutions for the evolving nuclear security landscape.

News and highlights
New research reveals that the radioactive isotope zirconium-88 is 100,000 times more likely than expected to absorb any room-temperature (“thermal”) neutron it encounters.
Our researchers and collaborators created a technique used to determine the shape of a neutron-rich ruthenium isotope.
