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…

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…

The new APD-Based Readout of the Crystal Barrel Calorimeter -- An Overview

TAPS Collaboration, C. Honisch, P. Klassen +47

The Crystal Barrel is an electromagnetic calorimeter consisting of 1380 CsI(Tl) scintillators, and is currently installed at the CBELSA/TAPS experiment where it is used to detect d…

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…
