Target and beam-target asymmetries for the reaction

S. Garni, V. L. Kashevarov, A. Fix +81

Background: Photoproduction of pion pairs allows to study sequential decays of nucleon resonances via excited intermediate states. Such decays are important e.g. for states which i…

First measurement of helicity-dependent cross sections in pi0-eta photoproduction from quasi-free nucleons

A. Käser, M. Dieterle, L. Witthauer +80

The helicity-dependent cross sections for the photoproduction of pairs have been measured for the first time. The experiment was performed at the tagged photon facility of t…

High-statistics measurement of the eta->3pi^0 decay at the Mainz Microtron

S. Prakhov, S. Abt, P. Achenbach +85

The largest, at the moment, statistics of 7x10^6 eta->3pi^0 decays, based on 6.2x10^7 eta mesons produced in the gamma p -> eta p reaction, has been accumulated by the A2 Collabora…

Determination of the scalar polarizabilities of the proton using beam asymmetry in Compton scattering

V. Sokhoyan, E. J. Downie, E. Mornacchi +73

The scalar dipole polarizabilities, and , are fundamental properties related to the internal dynamics of the nucleon. The currently accepted values of the proton p…

Photoproduction ofeta-pi pairs off nucleons and deuterons

A. Kaeser, F. Mueller, J. Ahrens +66

Quasi-free photoproduction of -pairs has been investigated from threshold up to incident photon energies of 1.4 GeV, respectively up to photon-nucleon invariant masses up to 1.…

Photoproduction of -pairs off protons and off neutrons

M. Dieterle, M. Oberle, J. Ahrens +71

Total cross sections, angular distributions, and invariant-mass distributions have been measured for the photoproduction of pairs off free protons and off nucleons bound i…
