pi mesons bremsstrahlung Hanson, A.O. Blecher, Marvin 2011-07-08T17:08:22Z 2011-07-08T17:08:22Z 10000-01-01 1968 "Cross sections for the coherent photoproduction of 71""0 mesons from He3(gammaHe3 -> pi°He 3) were measured for recoil angles of 200, 300, 400, and 500 from the direction of the incident photon. A gaseous He3 target was irradiated by 340 MeV bremsstrahlung; provided by the 'University of Illinois betatron. The He3 gas was maintained at liquid hydrogen temperature and at a pressure of slightly above one atmosphere. The recoil nuclei were observed with silicon semiconductor detectors. At least one gamma ray from the pion decay was detected with a lead glass Cherenkov counter. A coincidence between a semiconductor detector and the Cherenkov counter triggered an oscilloscope on which all pulses were then displayed and photographed. These photographs constitute the experimental data."
