Physicists move closer to listening in on sub-atomic conversation
Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing tools to allow them to listen in on the particles' gab fests and learn more about how they stick together to build our visible universe. The first complex calculations of a particle called the sigma have been carried out and published in Physical Review Letters.

Jefferson lab director honored with Energy Secretary Award
Hugh Montgomery, director of the Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), was awarded The Secretary's Distinguished Service Award by the Secretary of Energy earlier this year. This honor highlights Montgomery's contributions to the research programs at the DOE national labs, both as a world-leading researcher and as a more than 30-year DOE national laboratory employee.

Scientists mix matter and anti-matter to resolve decade-old proton puzzle
Fans of science and science fiction have been warned that mixing matter with anti-matter can yield explosive results. And that's just what physicists were counting on, in hopes of blowing wide open a puzzle that has confounded them for the last decade.

Snubbed protons tattle on neutron structure
Protons and neutrons are the fraternal twins of the sub-atomic world and the building blocks of all atomic nuclei. While similar in many respects, it's their differences that give them their unique properties. Now, scientists are exploiting these differences to gain deeper insight into these fundamental particles that build our visible universe.

Scientist wins energy award at technology event
Xin Zhao has won a World Technology Network award in the individual Energy category for innovative work of "the greatest likely long-term significance" in his field. Zhao designed and patented a supercapacitor that would use graphene. The invention could someday see batteries in electric vehicles and similar devices boosted or replaced by high-power, high-capacity, fast-charge/discharge energy storage systems using graphene.

Building block detectors for plants
While a plant's overall health can often be determined through simple observation, researchers sometimes need to see what's happening on the inside. That's where Jefferson Lab group leader Drew Weisenberger and his colleagues come in. They are working to develop tools that can image inside plants.

Result tickler: Lead nucleus may bury positive side under neutral facade
Results from the Lead (Pb) Radius Experiment (PREx), performed last year at Jefferson Lab, suggest that the nucleus of a lead atom buries its positive "personality" beneath a neutral exterior. The preliminary result is consistent with the idea that neutrons form a kind of "neutron skin" around the protons in the nucleus in heavy nuclei. It is important for understanding heavy nuclei and for theoretical equations that describe the life cycles of neutron stars.

Odd particle left out in the cold
The old saying birds of a feather flock together may also be true for the smallest bits of matter. According to a study recently published in Physical Review Letters, like particles inside protons and neutrons band together, leaving the odd one out.

Bright light/dark matter: Free-electron lasers enter the realm of particle physics
While two accelerators have been operating at Jefferson Lab for more than a decade, only one was known for its research probing the particles that make up our universe. But things have changed. A particle physics experiment recently performed with Jefferson Lab's Free-Electron Laser, powered by the lesser-known and smaller accelerator, has had its results published in Physical Review Letters.

'Skinny' pions sail through nucleus
A recent Jefferson Lab experiment may have demonstrated the onset of color transparency for pions, a necessary ingredient for interpreting related experimental results in nuclear and particle physics. The experiment was performed in Jefferson Lab's Experimental Hall C.

Spin in the neutron
Physicists were in a whirl after measurements in the '80s revealed that the spins of the individual building blocks of the proton don't add up to the proton's actual spin. The so-called "proton spin crisis" spurred efforts to pin down where protons -- and neutrons -- get their spin. Pioneering measurements in Jefferson Lab's Hall A have opened the door for measuring some suspected sources of the neutron's spin.
