Measurement of the 40Ar(e,$$\hbox {e}^{\prime }$$) elastic scattering cross section with a novel gas-jet target

M. Littich, L. Doria, Peter B. Brand, Patrick Achenbach et autres

Abstract We report on a measurement of elastic electron scattering on argon performed with a novel cryogenic gas-jet target at the Mainz Microtron accelerator MAMI. The luminosity is estimated with the thermodynamical parameters of the target and by comparison to a calculation …

Nuclear density dependence of polarization transfer in quasi-elastic A ( e , e ′ p ) reactions

T. Kolar, Wim Cosyn, C. Giusti, Patrick Achenbach et autres

The ratio of the transverse and longitudinal components of polarization transfer to protons in the quasielastic $(\stackrel{P\vec}{e},{e}^{\ensuremath{'}}\stackrel{P\vec}{p}\phantom{\rule{0.16em}{0ex}})$ reaction, ${P}_{x}^{\ensuremath{'}}/{P}_{z}^{\ensuremath{'}}$, is sensitive to the proton's electromagnetic form factor ratio, ${G}_{E}/{G}_{M}$. To explore density-dependent in-medium modifications, a comparison of polarization transfer ratios involving protons …

Nuclear density dependence of polarization transfer in quasi-elastic ${\rm A}(\vec{e},e' \vec{p})$ reactions

T. Kolar, Wim Cosyn, C. Giusti, Patrick Achenbach et autres

The ratio of the transverse and longitudinal component of polarization transfer to protons in the quasi-elastic $(\vec{e}, e^{\prime} \vec{p}\,)$ reaction, $P^{\prime}_x/P^{\prime}_z$, is sensitive to the proton's electromagnetic form factor ratio, $G_E/G_M$. To explore density-dependent in-medium modifications, a comparison of polarization transfer ratios …

Measurement of polarization transfer in the quasi-elastic $^{40}{\rm Ca}(\vec{e},e' \vec{p})$ process

T. Kolar, Patrick Achenbach, Mirco Christmann, M. O. Distler et autres

Polarization transfer to a bound proton in polarized electron knock-out reactions, $\mathrm{A}(\vec{e},e^{\prime}\vec{p})$, is a powerful tool to look for in-medium modification of the bound proton. It requires comparison to calculations which consider the many-body effects accompanying the quasi-free process. We report here …

Low-$Q^2$ elastic electron-proton scattering using a gas jet target

Y. Wang, J. C. Bernauer, B. S. Schlimme, Patrick Achenbach et autres

In this paper, we describe an experiment measuring low-$Q^2$ elastic electron-proton scattering using a newly developed cryogenic supersonic gas jet target in the A1 three-spectrometer facility at the Mainz Microtron. We measured the proton electric form factor within the four-momentum transfer range …
