We report the first measurement using a solid polarized target of neutron electric form factor G(n)(E) via d-->(e-->,e(')n)p. was determined from beam-target asymmetry in scattering longitudinally electrons deuterated ammonia ( 15ND3). The performed Hall C at Thomas Jefferson National Accelerator Facility quasifree kinematics with polarization perpendicular to momentum transfer. were detected magnetic spectrometer coincidence neutrons large angle segmented detector. find =...
We report the results from a systematic study of quasielastic $(e,{e}^{\ensuremath{'}}p)$ reaction on $^{12}\mathrm{C},\phantom{\rule{0.5em}{0ex}}^{56}\mathrm{Fe}$, and $^{197}\mathrm{Au}$ performed at Jefferson Lab. have measured nuclear transparency extracted spectral functions (corrected for radiation) over ${Q}^{2}$ range $0.64--3.25\phantom{\rule{0.5em}{0ex}}{(\text{GeV}∕c)}^{2}$ all three nuclei. In addition, we separated longitudinal transverse 0.64...
The ( ${e,e}^{\ensuremath{'}}p$) reaction was studied on targets of C, Fe, and Au at momentum transfers squared ${Q}^{2}$ 0.6, 1.3, 1.8, $3.3{\mathrm{GeV}}^{2}$ in a region kinematics dominated by quasifree electron-proton scattering. Missing energy missing distributions are reasonably well described plane wave impulse approximation calculations with $A$ dependent corrections that measure the attenuation final state protons.
Auditory temporal processing is a vital component of auditory stream segregation, or the process in which complex sounds are separated and organized into perceptually meaningful objects. Temporal can degrade prior to hearing loss, suggested be contributing factor difficulties with speech-in-noise perception normal-hearing listeners. The current study tested this hypothesis middle-aged adults—an under-investigated cohort, despite being age group where first reported. In 76 participants, three...
Cochlear synaptic loss (termed cochlear synaptopathy) has been suggested to contribute suprathreshold hearing difficulties. However, its existence and putative effects in humans remain inconclusive, largely due the heterogeneous methods used across studies indirectly evaluate health of synapses. There is a need standardize proxies synaptopathy appropriately compare interpret findings studies. Early auditory evoked potentials (AEPs), including compound action potential (AP)/Wave I brainstem...
A separation of the longitudinal and transverse 12C(e,e′p) cross sections in quasifree region has been performed parallel kinematics at Q2 0.64 1.8 GeV2 for initial proton momentum <80 MeV. The separated spectral functions Q2=0.64GeV2 show significant differences missing energy between 25 60 MeV indicating a breakdown single nucleon knockout picture. exhibit definite transfer dependence.Received 29 November 1999DOI:https://doi.org/10.1103/PhysRevC.61.061602©2000 American Physical Society
