title: "gn-dcs11" of "Quasifree photoproduction of $\eta$ mesons off protons and neutrons"

description: Differential cross section at W= 1.5450 GeV
description: A2 Collaboration at MAMI.
Differential and total cross sections for the quasifree reactions
$\gamma p \to \eta p$ and $\gamma n \to \eta n$ have been determined
at the MAMI-C electron accelerator by using a liquid deuterium
target. Photons were produced via bremsstrahlung from the 1.5 GeV
incident electron beam and energy tagged with the Glasgow photon
tagger. Decay photons of the neutral decay modes $\eta \to 2\gamma$
and \eta \to 3\pi^0$ and coincident recoil nucleons were detected
in a combined setup of the Crystal Ball and the TAPS calorimeters.
The $\eta$-production cross sections were measured in coincidence
with recoil protons, recoil
neutrons, and in an inclusive mode without a condition on recoil
nucleons, which allowed a check of the internal consistency of 
the data. The effects from nuclear Fermi motion were removed by
a kinematic reconstruction of the final-state invariant mass and
possible nuclear effects on the quasifree cross section were
investigated by a comparison of free and quasifree-proton data.
The systematic uncertainties for the proton analyses are about
6%–7%, for the neutron analyses are around 12%.
