Jefferson Lab Published Journal Articles Dec. 8-12

Remember to submit your papers for approval to the Jefferson Lab Publications database.

Center for Theoretical and Computational Physics

Quantum Monte Carlo methods have proved very valuable in the study of the structure and reactions of light nuclei and nucleonic matter starting from realistic nuclear interactions and currents. A new paper presents a variety of results for a number of observables, including the low-lying spectra of light nuclei, form factors, transition matrix elements, electroweak response functions relevant in electron and neutrino scattering, and the properties of dense nucleonic matter in neutron stars. A coherent picture of nuclear structure and dynamics emerges.

Beware of Holiday Carjacking Scams
The U.S. Army Criminal Investigation Command is warning service members about a new carjacking scam targeting unsuspecting holiday shoppers. Criminals will place a $100 bill on an individual's windshield under the wiper blade; while the victim is distracted and gets out to retrieve the cash, the criminals approach the vehicle and rob the victim of their belongings and car. Should anyone discover money on their vehicle, they should quickly move to a safe, public location and notify law enforcement or security personnel immediately. Lock your doors, and do not get out of the vehicle to retrieve the bill. More information and parking lot safety tips can be found here.
