Download or read book Measurement of Two-body Deuteron Photodisintegration at High Photon Energies and Theta written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report preliminary results from a measurement of the process 2H(.gamma., p)n at theta/sub CM/ = 90° and for photon energies between 0.8 and 1.6 GeV. The results are compared to a conventional calculation based on meson-exchange and to models based on sub-nucleonic degrees of freedom. We find strong disagreement with the meson-exchange calculation, and best agreement with simple constituent counting at the highest energies.
