Eta-prime photoproduction on the proton for photon energies from 1.527 to 2.227 GeV
M. Dugger et al.
Differential cross sections for the reaction gamma p -> eta-prime p have been measured 
with the CLAS spectrometer and a tagged photon beam with energies from 1.527 to 2.227 GeV. 
The results reported here possess much greater accuracy than previous measurements. 
Analyses of these data indicate for the first time the coupling of the etaprime N channel 
to both the S_11(1535) and P_11(1710) resonances, known to couple strongly to the 
eta N channel in photoproduction on the proton, and the importance of j=3/2 resonances 
in the process.
