Download or read book Measurement of the High Energy Two-Body Deuteron Photodisintegration Differential Cross Section written by and published by . This book was released on 2001 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first measurements of the d(gamma, p)n differential cross section at forward angles and photon energies above 4 GeV were performed at the Thomas Jefferson National Accelerator Facility (JLab). The results indicate evidence of an angular dependent scaling threshold. Results at theta{sub cm} = 37{sup o} are consistent with the constituent counting rules for E{sub gamma}H" 4 GeV, while those at 70{sup o} are consistent with the constituent counting rules for E{sub gamma} H" 1.5 GeV.
