High-Precision Neutron-Induced Gamma Production Cross Section Measurements Using Associated Particle Imaging
A novel technique utilizing Associated Particle Imaging (API) enables high-precision absolute measurements of gamma-ray production cross sections for 14 MeV neutron-induced reactions. This method tags neutrons via associated alpha particles, allowing for background suppression and precise neutron fl…
AT-TPC in SOLARIS Enables Precise Spectroscopy of 11Be, Confirming Positive Parity for 3.40 MeV State
The 10Be(d,p)11Be transfer reaction was measured in inverse kinematics at 9.6 MeV/u using the AT-TPC coupled with the SOLARIS solenoid, marking the first high-luminosity transfer experiment without degrading excitation energy or scattering angle resolutions. Distorted-wave Born approximation analysi…
Photoproduction of quasi-bound omega mesons in nuclei via the (gamma,p) reaction
This paper proposes using the (gamma,p) reaction to produce quasi-bound omega mesons in nuclei. An effective Lagrangian, incorporating chiral SU(3) symmetry and vector meson dominance, is used to model the omega-nuclear potential. The authors predict that bound omega states can be observed in the mi…
Scientific Case for CEBAF 22 GeV Upgrade Refined
This document summarizes the outcomes of the "Science at the Luminosity Frontier: Jefferson Lab at 22 GeV" workshop. The primary goal was to critically assess and refine the scientific case for a proposed energy upgrade of the Continuous Electron Beam Accelerator Facility (CEBAF) to 22 GeV. This doc…
