High precision measurements of the proton elastic electromagnetic form factors and their ratio at $Q^2$ = 0.50, 2.64, 3.20, and 4.10 GeV$^2$

I.A Qattan, J Arrington, K. Aniol, O. K. Baker et autres

The advent of high-intensity, high-polarization electron beams led to significantly improved measurements of the ratio of the proton's charge to electric form factors, GEp/GMp. However, high-$Q^2$ measurements yielded significant disagreement with extractions based on unpolarized scattering, raising questions about the reliability of …

Nuclear charge radius of He8

M. Dubois, A. C. C. Villari, N. Lecesne, R. Alvès-Condé et autres

The root-mean-square (rms) nuclear charge radius of He8, the most neutron-rich of all particle-stable nuclei, has been determined for the first time to be 1.93(3) fm. In addition, the rms charge radius of He6 was measured to be 2.068(11) fm, in excellent …

Measurement of the EMC effect in light and heavy nuclei

J. Arrington, J. Bane, A. V. Daniel, N. Fomin et autres

The authors present landmark measurements of the nuclear dependence of quark momentum distributions in nuclei, also known as the EMC effect. The experiment covers a wide range of nuclei and focuses on quarks carrying a large part of a nucleon's longitudinal momentum. …

Measurement of the Nucleon $F^n_2/F^p_2$ Structure Function Ratio by the Jefferson Lab MARATHON Tritium/Helium-3 Deep Inelastic Scattering Experiment

MARATHON Collaboration, D. Abrams, H. Albataineh, B. Aljawrneh et autres

The ratio of the nucleon $F_2$ structure functions, $F_2^n/F_2^p$, is determined by the MARATHON experiment from measurements of deep inelastic scattering of electrons from $^3$H and $^3$He nuclei. The experiment was performed in the Hall A Facility of Jefferson Lab and used …

The neutron electric dipole moment experiment at the Spallation Neutron Source

K. K. H. Leung, M.W. Ahmed, Ricardo Alarcón, Alina Aleksandrova et autres

Novel experimental techniques are required to make the next big leap in neutron electric dipole moment experimental sensitivity, both in terms of statistics and systematic error control. The nEDM experiment at the Spallation Neutron Source (nEDM@SNS) will implement the scheme of Golub …

Impact of O16(e,e′α)C12 measurements on the C12(α,γ)O16 astrophysical reaction rate

R. J. Holt, B. W. Filippone

The $^{12}\mathrm{C}(\ensuremath{\alpha},\ensuremath{\gamma})^{16}\mathrm{O}$ reaction, an important component of stellar helium burning, has a key role in nuclear astrophysics. It has direct impact on the evolution and final state of massive stars and also influences the elemental abundances resulting from nucleosynthesis in such stars. …
