Particle physicists at the Spallation Neutron Source recently made the first observation of the elusive neutrino's most common interaction with matter with a pint-sized detector.
OAK RIDGE, Tenn., March 26, 2018 - If equal amounts of matter and antimatter had formed in the Big Bang more than 13 billion years ago, one would have annihilated the other upon meeting
It is essential to determine neutron capture reaction cross sections on heavy unstable nuclei to better understand the rapid neutron capture process in neutron star mergers and in core collapse supernovae.
A priority target of gamma ray astronomy, observing the decay of radioactive 18F nuclei in space can help diagnose the mechanism of nova explosions which create and disperse this radionuclide.
Coincidence measurements of protons and gamma rays produced via the (d,p gamma) transfer reaction with neutron-rich radioactive beams can give high resolution information on single-particle states in these exotic nuclei.
The 306 keV resonance in the 35Cl nucleus may, depending on its properties, play a dominant role in the capture of protons on 34S. This reaction serves as a step in a larger series of reactions which fuels the thermonuclear runaway in nova explosions.
New mixtures of liquid scintillators have been developed for a time-of-flight neutron detector array with position sensitivity, high light output, and excellent pulse shape discrimination (PSD) to be used for studies of nuclear reactions producing neutrons
Using first-principles calculations, ORNL researchers computed the nuclear structure of nickel-78 to improve understanding of the origin, organization, and interactions of stable matter.
Two researchers in the ORNL Physics Division and the University of Tennessee (NICS) addressed the stochasticity and efficiency of core-collapse supernova explosions by using a highly simplified supernova model.
The nEDM@SNS experiment will measure the electric dipole moment of the neutron - essentially the roundness of its charge distribution.
