Your statement that "...there are no previous measurements for double<br>
polarization observables" desperately needs to be preceded by a<br>
statement of exactly what process you're talking about. CLAS has<br>
published several double polarization observables in multiple reactions<br>
over the years, as have (I suspect) several other facilities. I would<br>
suggest rewording the second sentence as<br>
<br>
"In the eta photoproduction process on the proton, there are relatively<br>
few single polarization measurements, compared to unpolarized<br>
differential cross section measurements, and no double polarization<br>
measurements." Some wordsmithing is still needed there.<br>
