The NUCLEI collaboration will be using some of the worlds most powerful supercomputers, including ORNL’s TITAN, to calculate properties and reactions of atomic nuclei.
The SciDAC Towards Exascale Astrophysics of Mergers and Supernovae (TEAMS) Collaboration is investigating supernovae explosions and neutron-star mergers that create atomic elements heavier than iron and predict such as gravitational waves from these events.
The GODDESS system will be used to measure reactions with neutron-rich unstable nuclei to understand the evolution of shell structure and neutron capture rates relevant for the r-process in neutron star mergers and in core-collapse supernovae.
The Nab project is an experiment at the SNS that will search for new physics beyond the Standard Model via a high-precision measurement of the "a" and "b" neutron decay parameters.
NPDGamma and n3He - the first two experiments at the Spallation Neutron Source (SNS) Fundamental Neutron Physics Beamline (FNPB) - measured parity-violating (PV) asymmetries in neutron capture in light nuclear systems in order to elucidate the weak interaction in hadronic systems.Â
The synthesis of the heaviest nuclei and studies of their properties expands our understanding of the extent and structure of the atomic and nuclear worlds. Recently, ORNL was recognized by the International Union of Pure and Applied Chemistry for contributions to the discovery of two new elements, tennessine (atomic number 117) and moscovium (atomic number 115).
The COHERENT experiment makes use of the intense, high-quality neutrinos from the Spallation Neutron Source to measure neutrino-nucleus scattering. COHERENT made the first of coherent elastic neutrino-nucleus scattering (CEvNS) in 2017 and its ongoing program with multiple target nuclei will probe physics beyond the standard model, and address questions in nuclear physics and astrophysics.
The High Energy Nuclear Physics Group studies the features of both high temperature and low temperature Quantum Chromo Dynamics (QCD) in strongly interacting matter using ultra high energy collisions of p+p, p+Pb and Pb+Pb at the Large Hadron Collider (LHC) with the A Large Ion Collider Experiment. (ALICE). Presently, the ORNL group leads a large collaboration of US groups conducting a central Barrel Tracking Upgrade (BTU) of the ALICE experiment for a new program of measurements on the Quark Gluon Plasma starting in 2002.
