When odds are equal, particles paired up with others of the same kind more often than once thought. The protons and neutrons, which make up the atom's nucleus, frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how pack
Two of tritium’s three nucleons can form short-range correlations that include a proton and one of its neutrons or two neutrons. Credit: DOE’s Jefferson LabThe protons and neutrons, which make up the’s nucleus, frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how packed the nucleus is. The work was conducted at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility.
“Tritium is one proton and two neutrons, and helium-3 is two protons and one neutron. By comparing tritium and helium-3, we can assume that neutron-proton pairs in tritium are the same as neutron-proton pairs in helium- 3. And tritium can make one additional neutron-neutron pair, and helium-3 can make one additional proton-proton pair,” Li explained.
“The ratio we extracted in this experiment is four neutron-proton pairs per each proton-proton or neutron-neutron pair,” Li revealed. “In the nucleon-nucleon interaction, there’s the “tensor” piece, which generates neutron-proton pairs. And there’s a shorter-range “core” that can generate proton-proton pairs. When the nucleons are further apart, as in these very light nuclei, you may get a different balance between these interactions.”
