Analytical calculation of Coulomb corrections to pair production at intermediate photon energies
R. N. Lee, A. I. Milstein, V. M. Strakhovenko
First correction to the high-energy asymptotics of the total photoproduction cross section in the electric field of a heavy atom is obtained with the exact account of this…
Linear to Circular Polarisation Conversion using Birefringent Properties of Aligned Crystals for Multi-GeV Photons
NA59 Collaboration, A. Apyan, R. O. Avakian +27
We present the first experimental results on the use of a thick aligned Si crystal acting as a quarter wave plate to induce a degree of circular polarisation in a high energy linea…
Coherent Pair Production by Photons in the 20-170 GeV Energy Range Incident on Crystals and Birefringence
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The cross section for coherent pair production by linearly polarised photons in the 20-170 GeV energy range was measured for photon aligned incidence on ultra-high quality diamond…
