Measurement of the Gerasimov-Drell-Hearn integrand for proton and deuteron from 200 to 1400 MeV
P. Pedroni, F. Afzal, S. Abt +59
New data for the total inclusive helicity-dependent cross section for the proton and deuteron were obtained in the photon energy interval 200-1400 MeV. The experiment was performed…
Three-Nucleon Dynamics in the dp breakup collisions at 190 MeV/nucleon using the WASA detector at COSY-Jülich
P. Adlarson, W. Augustyniak, W. Bardan +87
The differential cross section for the H breakup reaction at deuteron beam energy of 380 MeV has been determined with high precision for 189 angular configurations o…
New high-statistics measurement of the Dalitz decay at the Mainz Microtron
S. Prakhov, L. Heijkenskjöld, S. Abt +69
The Dalitz decay has been measured with the highest statistical accuracy obtained so far in the reaction with the A2 tagged-photon facility at the M…
Helicity dependent cross sections for the photoproduction of pairs from quasi-free nucleons
A2 Collaboration, D. Ghosal, V. Sokhoyan +71
Photoproduction of -pairs from quasifree nucleons bound in the deuteron has been investigated to study the helicity dependence of this reaction. Measurements with a liq…
Neutron polarisation transfer, , in photoproduction off the proton
M. Bashkanov, D. P. Watts, S. J. D. Kay +63
We report a first measurement of the double-polarisation observable, , in photoproduction off the proton. The double-polarisation observable represents the t…
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…
Cross Section for measured at Mainz/A2
W. J. Briscoe, M. Hadzimehmedovi, A. E. Kudryavtsev +89
The differential cross section evaluated for 27 energy bins span the photon-energy range 290-813 MeV (W = 1.195-1.553 GeV) and the pion c.m. polar production angles,…
Measurement of the beam-helicity asymmetry in photoproduction of pairs on carbon, aluminum, and lead
V. Sokhoyan, S. Prakhov, A. Fix +88
The beam-helicity asymmetry was measured, for the first time, in photoproduction of pairs on carbon, aluminum, and lead, with the A2 experimental setup at MAMI. The result…
Photoproduction of {\boldmath{}} Mesons off Protons and Neutrons in the Second and Third Nucleon Resonance Region
M. Dieterle, D. Werthmüller, S. Abt +81
Photoproduction of mesons off quasi-free nucleons bound in the deuteron allows to study the electromagnetic excitation spectrum of the neutron and the isospin structure of the exci…
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…
