Display of probability densities for data from a continuous distribution

Based on cumulative distribution functions, Fourier series expansion and Kolmogorov tests, we present a simple method to display probability densities for data drawn from a continuous distribution. It is often more efficient than using histograms.Comment: 5 pages, 4 figures, presented at Computer Simulation Studies XXIV, Athens, GA, 201

Measurement of the Generalized Polarizabilities of the Proton in Virtual Scattering at Q2=0.92 and 1.76 GeV2: I. Low Energy Expansion Analysis

Virtual Compton Scattering is studied at the Thomas Jefferson National Accelerator Facility at low Center-of-Mass energies, below pion threshold. Following the Low Energy Theorem for the $ep \to ep \gamma$ process, we obtain values for the two structure functions Pll-Ptt/epsilon and Plt at four-momentum transfer squared Q2=0.92 and 1.76 GeV2.Comment: 4 pages, 2 figures, to be submitted to PRL.

Dynamical relativistic effects in quasielastic 1p-shell proton knockout from O-16

We have measured the cross section for quasielastic 1p-shell proton knockout in the O-16(e,e'p) reaction at omega = 0.439 GeV and Q(2) = 0.8 (GeV/c)(2) for missing momentum P-miss less than or equal to 355 MeV/c. We have extracted the response functions RL+TT, R-T, R-LT, and the left-right asymmetry, A(LT), for the 1p(1/2) and the 1p(3/2) states. The data are well described by relativistic distorted wave impulse approximation calculations. At large P-miss, the structure observed in A(LT) indicates the existence of dynamical relativistic effects

Dynamics of the O-16(e,e(l)p) reaction at high missing energies

We measured the cross section and response functions for the quasielastic O-16(e, e 'p) reaction for missing energies 25 less than or equal to E-m less than or equal to 120 MeV at missing momenta P-m less than or equal to 340 MeV/c. For 25 < E-m < 50 MeV and P-m approximate to 60 MeV/c, the reaction is dominated by a single ls(1/2) proton knockout. At larger P-m, the single-particle aspects are increasingly masked by more complicated processes. Calculations which include pion exchange currents, isobar currents, and short-range correlations account for the shape and the transversity, but for only half of the magnitude of the measured cross section

Polarization transfer in the O-16((e)over-right-arrow,e '(p)over-right-arrow)N-15 reaction

The first ((e) over right arrow ,e'(p) over right arrow) polarization transfer measurements on a nucleus heavier than deuterium have been carried out at Jefferson Laboratory. Transverse and longitudinal components of the polarization of protons ejected in the reaction O-16((e) over right arrow ,e'(p) over right arrow) were measured in quasielastic perpendicular kinematics at a Q(2) of 0.8 (GeV/c)(2). The data are in good agreement with state of the art calculations
