Abstract

The differential cross sections for the γ(1S), γ(2S), and γ(3S) states and the γ(1S) polarization were measured. Fits of nonrelativistic quantumchromodynamics (NRQCD) matrix elements could describe the cross sections. The polarization systematic uncertainties were also indicated. The polarization measurement was made by fitting the shape of the uncorrected data.
