title: "dcs32_16" of "Helicity-dependent cross sections and double-polarization observable E in eta photoproduction from quasi-free protons and neutrons"

description: Diff. cross section for helicity-3/2 at W= 1.712 GeV
description: A2 Collaboration at MAMI.
Precise helicity-dependent cross sections and the
double-polarization observable E were measured for $\eta$
photoproduction from quasifree protons and neutrons bound in the
deuteron. The $2\gamma$ and $3\pi^0$ decay modes were used to optimize
the statistical quality of the data and to estimate systematic
uncertainties. The measurement used the A2 detector setup at the
tagged photon beam of the electron accelerator MAMI in Mainz.
A longitudinally polarized deuterated butanol target was used in
combination with a circularly polarized photon beam from
bremsstrahlung of a longitudinally polarized electron beam. The
reaction products were detected with the electromagnetic
calorimeters Crystal Ball and TAPS, which covered 98% of the full
solid angle. The main systematic uncertainty of the E asymmetry
is related to the measurement of the beam and target
polarizations. The uncertainty of the photon polarization degree
was determined to be ±2.7%. The uncertainty of the target
polarization was estimated as ±10%.
