To probe CP violation in the leptonic sector using GeV energy neutrino beams current and future experiments argon detectors, precise models of complex underlying antineutrino interactions are needed. The E12-14-012 experiment at Jefferson Lab Hall A was designed to perform a combined analysis inclusive exclusive electron scatterings on both ($N = 22$) titanium ($Z nuclei beams. measurement nucleus provides essential information understand scattering argon, large contribution which comes from...
The success of the ambitious programs both long- and short-baseline neutrino-oscillation experiments employing liquid-argon time-projection chambers will greatly rely on precision with which weak response argon nucleus can be estimated. In E12-14-012 experiment at Jefferson Lab Hall A, we have studied properties by scattering a high-quality electron beam off high-pressure gaseous target. Here, present measured $^{40}$Ar$(e,e^{\prime})$ double differential cross section incident energy...

Here, we report full results of analysis data set corresponding to beam energy 2.222 GeV, and spanning missing momentum range $15 \lesssim p_m 300$ MeV/c $12 E_m 80$ MeV. reduced section, determined as function $p_m$ $E_m$ with $\approx$4\% accuracy, been fitted Monte Carlo simulations involving model spectral including effects final state...
The E12-14-012 experiment, performed in Jefferson Lab Hall A, has measured the (e,e'p) cross section parallel kinematics using a natural titanium target. Here, we report full results of analysis data set corresponding to beam energy 2.2 GeV, and spanning missing momentum range 15 <= pm 250 MeV/c 12 Em 80 MeV. reduced been with ~7% accuracy as function both energy. We compared our Monte Carlo simulations model spectral including effects final state interactions. overall agreement between is...
The spin-structure functions $g_1$ and $g_2$, the spin-dependent partial cross-section $\sigma_\mathrm{TT}$ have been extracted from polarized cross-sections differences, $\Delta \sigma_{\parallel}\hspace{-0.06cm}\left(\nu,Q^{2}\right)$ \sigma_{\perp}\hspace{-0.06cm}\left(\nu,Q^{2}\right)$ measured for $\vec{^\textrm{3}\textrm{He}}(\vec{\textrm{e}},\textrm{e}')\textrm{X}$ reaction, in E97-110 experiment at Jefferson Lab.

The NaI:Tl crystals were early investigated and used for wide application fields due to high light yield crystal growth advantages. So far, the absolute yields of have typically been known be 40 ph/keV. However, it varies widely, far from theoretical estimation. Since better sensitivity is important low mass dark matter search. Therefore, necessary use crystal, should measured with accuracy. In this work, we single photoelectron technique measuring 35 various sizes different vendors. There...
We propose an overall procedure for measuring and unfolding fast neutron spectra using a trans-stilbene scintillation detector. Detector characterization was described, including the information on energy calibration, detector resolution, nonproportionality response. The digital charge comparison method used investigation of neutron-gamma Pulse Shape Discrimination (PSD). A pair values 600 ns pulse width 24 delay time found as optimized conditions PSD. fitting technique introduced to...
A first gamma-ray study of 47,49Cl spectroscopy was performed at the Radioactive Isotope Beam Factory with 50Ar projectiles 217 MeV/nucleon, impinging on liquid hydrogen target MINOS device.

The Jefferson Lab (JLab) Hall A E97110 experiment performed a precise measurement of the neutron spin structure functions at low Q2 by using polarized 3He target as an effective target. goals are to make bench-mark test Chiral Perturbation Theory calculations and check Gerasimov-Drell-Hearn (GDH) sum rule extrapolating integral real photon point. data were taken in two experimental run periods. first period covered lowest points but with defective equipment which complicates analysis. second...
