Photoproduction of Low-Energy Charged Pions from Deuterium

Abstract

The 7T-7r and K-TT interactions will also possess a diffraction scattering and total cross section of the form predicted above, although these interactions cannot be checked by any current experimental data. One experiment would be particularly useful at present to check our predictions. From the effect of the o> meson on the pp and pp cross sections, we conclude that K-p and K-p total cross sections will be approximately the same above 10 BeV, and will have the formAccurate measurements have been made of the ir~/ir + photoproduction ratio on deuterium, in the gammaray energy range 165-210 MeV, for several angles: 155°, 125°, 90° (center-of-mass system) and along Baldin's kinematical line. These last data are new contributions: 7r~/V +== l-20:k0.03 averaged between 165 and 180 MeV. The others are improvements of the accuracy of previous data. The comparison with Ball's theory, corrected for taking into account the I~\ phase shifts, gives for the coupling constant A for y-7r-p the value: 0.25<+A/e<0.75. MEV)

Photopion Production From Deuterium Near Threshold

“…76 The Coulomb corrections of Baldin were used to correct for final-state Coulomb interactions. These corrected ratios are in good agreement with the results of other workers, [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]47 and with the dispersion relations of CGLN. The results of this experiment are shown in Fig.…”
