GOOGLE-DOCS COMO HERRAMIENTA PARA LA DIRECCIÓN ONLINE DE PROYECTOS FINALES EN LAS TITULACIONES DEL EEES

The purpose of the present paper is to share our first assessments of an experience using the software Google-Docs as a monitoring tool for guiding various final degree / master projects. This innovative practice meets one of the challenges of implementation of the European Higher Education Area, namely, in the design of degree and master qualifications, the accomplishment of a final project is included as part of the 240 and 60 ECTS, respectively.La finalidad del presente trabajo es compartir nuestras primeras valoraciones sobre una experiencia de utilización del software GoogleDocs como herramienta de seguimiento para la dirección de distintos trabajos final de carrera/máster. Esta práctica innovadora responde a uno de los retos que plantea la implantación del Espacio Europeo de Educación Superior: en la estructura de las titulaciones de Grado y Máster se incluye la realización de un proyecto final formando parte de los 240 y 60 créditos ECTS, respectivament

Investigation of the Exclusive ^{3}He(e,e'pn)p Reaction

Cross sections for the ^{3}He(e,e'pn)p reaction were measured for the first time at energy transfers of 220 and 270 MeV for several momentum transfers ranging from 300 to 450 MeV/c. Cross sections are presented as a function of the momentum of the recoil proton and the momentum transfer. Continuum Faddeev calculations using the Argonne V18 and Bonn-B nucleon-nucleon potentials overestimate the measured cross sections by a factor 5 at low recoil proton momentum with the discrepancy becoming much smaller at higher recoil momentum.Comment: 5, pages, 3 figure

Measurement of the asymmetries in 3He→ \overrightarrow{\sf He}(¯e, e′p)d and 3He→ \overrightarrow{\sf He}(¯e, e′p)np

Abstract.: The electron target asymmetries A || and A⊥ with target spin parallel and perpendicular to the momentum transfer \ensuremath{\boldsymbol{q}} were measured for both the two- and three-body breakup of 3He in the 3 $\overrightarrow{\rm He}$ (¯e, e'p)-reaction. Polarized electrons were scattered off polarized 3He in the quasielastic regime in parallel kinematics with the scattered electron and the knocked-out proton detected using the Three-Spectrometer Facility at MAMI. The results are compared to Faddeev calculations which take into account Final-State Interactions as well as Meson Exchange Currents. The experiment confirms the prediction of a large effect of Final-State Interactions in the asymmetry of the three-body breakup and of an almost negligible one for the two-body breaku

Beam-helicity asymmetry in photon and pion electroproduction in the Delta(1232) resonance region at Q^2= 0.35 (GeV/c)^2

The beam-helicity asymmetry has been measured simultaneously for the reactions (e p \to e p \gamma) and (e p \to e p \pi^0) in the $\Delta (1232)$ resonance region at $Q^2=$ 0.35 (GeV/c)$^2$. The experiment was performed at MAMI with a longitudinally polarized beam and an out-of-plane detection of the proton. The results are compared with calculations based on Dispersion Relations for virtual Compton scattering and with the MAID model for pion electroproduction. There is an overall good agreement between experiment and theoretical calculations. The remaining discrepancies may be ascribed to an imperfect parametrization of some $\gamma^{(*)} N \to \pi N$ multipoles, mainly contributing to the non-resonant background. The beam-helicity asymmetry in both channels ($\gamma$ and $\pi^0$) shows a good sensitivity to these multipoles and should allow future improvement in their parametrization.Comment: 7 pages, 8 figures, version to appear in EPJ

³He(<i>e,e′pp</i>) and ³He(<i>e,e′pn</i>) reactions at AmPS and MAMI

This paper reports on measurements of the &lt;sup&gt;3&lt;/sup&gt;He(&lt;i&gt;e,e′pp&lt;/i&gt;) reaction measured at AmPS and the &lt;sup&gt;3&lt;/sup&gt;He(&lt;i&gt;e,e′pn&lt;/i&gt;) reaction measured at MAMI. The measurements were performed in similar kinematics to allow a comparison to be made between the cross sections of the two reactions. Results are shown for both reactions together with a comparison for the &lt;sup&gt;3&lt;/sup&gt;He(&lt;i&gt;e,e′pp&lt;/i&gt;) data with continuum Faddeev calculations

Measurement of the asymmetries in (³He) over-right-arrow((e)over-right-arrow, e'p)d and (³He) over-right-arrow((e)over-right-arrow, e'p)np

The electron target asymmetrics A(parallel to) and A(perpendicular to) with target spin parallel and perpendicular to the momentum transfer q were measured for both the two- and three-body breakup of He-3 in the He-3(e,e`p)- reaction. Polarized electrons were scattered off polarized He-3 in the quasielastic regime in parallel kinematics with the scattered electron and the knocked-out proton detected using the Three-Spectrometer Facility at MAMI The results are compared to Faddeev calculations which take into account Final-State Interactions as well as Meson Exchange Currents. The experiment confirms the prediction of a, large effect of Final-State Interactions in the asymmetry of the three-body breakup and of an almost negligible one for the two-body breakup
