A major goal of nuclear theory is to explain the spectra and stability of nuclei in terms of effective many-body interactions amongst the nucleus' constituents - protons and neutrons. A new study shows, using quantum Monte Carlo calculations accurate to ≤ 2% of the binding energy, that two- and three-nucleon chiral interactions lead to predictions for the energy levels and level ordering of nuclei in the mass range A = 4 - 12 in very satisfactory agreement with experimental data. These chiral interactions have been constrained by fitting experimental bound- and scattering-state observables in the two- and three-nucleon sectors only.

Check Stockroom Inventory Before Submitting a Purchase Request
If for some reason you cannot use what is available in the stockroom, or the item is not stocked or in re-utilization (formerly known as free stock), annotate your reason in the "PR Notes block" or send an email to firstname.lastname@example.org or email@example.com. If you require assistance navigating through the E-commerce/GSS system, call Don Brown in the stockroom, x6297.

Radiation Workers Reminded to Notify RadCon of Medical Radiation Exposures
Your radiation dose at Jefferson Lab is gathered for occupational purposes only. But, in some cases, exposure to medical radiation can affect your occupational exposure record. If you are a radiation worker and are administered a medical radiopharmaceutical (usually done by injection), please inform the RadCon dosimetry staff. They have a specific procedure to follow, including gathering information regarding the type and amount of radionuclide used. This helps ensure your occupational dose record is accurate and allows RadCon to assess any impact you may have on the work environment after radiopharmaceutical administration. See full memo online here.

Lab Community Invited to Summer Interns Poster Session on Aug. 4
More than two dozen interns – participants from this year's Science Undergraduate Laboratory Internships (SULI) program, and the Research Experiences for Undergraduates (REU) program will be presenting the posters they developed based on their work or research projects. The students are eager to answer questions and to discuss their work.

Aug. 14 Class Date Set for New SOTR Training
Anyone who has recently been tasked to serve as a SOTR (or will be tasked) on any project at Jefferson Lab is required to attend this training. Attending this class is one part of the certification process for all SOTRs. The registration deadline is 5 p.m. on Friday, Aug. 11. Participants can register in the Learning Management System:
Questions regarding this training or the SOTR certification process may be directed to Mitch Laney, x5338.
