The Jefferson Lab Activity Group (JAG) was formed to enhance employee morale through various recreational, social, and athletic activities. Part of JAG's overall function is to promote and implement new ideas in support of DOE and DC policies. JAG also monitors new and existing recreational programs to ensure benefit to the greatest cross section of the lab community.
Physicists develop a universal function that suggests that proton-neutron pairs in the nucleus may explain why quarks inside nuclei have lower average momenta than predicted.
A new study has confirmed that increasing the number of neutrons as compared to protons in the atom’s nucleus also increases the average momentum of its protons.
The determination of the pressure distribution inside the proton is the first measurement of a mechanical property of a subatomic particle. The measurement found that the proton’s building blocks, quarks, are subjected to a pressure of 100 decillion Pascal (1035) near the center of a proton, which is about 10 times greater than the pressure in the heart of a neutron star.
