Two-body photodisintegration of the deutron at high energy: Experiment NE17 at SLAC
- and others
Experiment NE17 was granted three days of beam time during the last NPAS run at SLAC. During that time, the cross section data for the {gamma}d {yields} pn reaction were extended up to 2.8 GeV at {theta}{sub cm} = 90{degrees} and up to 4.2 GeV at {theta}{sub cm} = 37{degrees}. Data were also taken at {theta}{sub cm} = 37{degrees} 53{degrees}, and 90{degrees} at E{gamma} = 1.6 GeV so that a complete angular distribution would be available at this energy where an Enhancement at a large angle (143{degrees}) was found during experiment NE8. The results indicate the surprising feature that the cross sections at 90{degrees} and 53{degrees} follow the quark counting rule prediction, while those at 37{degrees} do not. Perhaps this indicates that p{sub T}{sup 2} is a controlling variable in the approach to asymptotic scaling. A manuscript was accepted for publication.
