Photoproduction of Charged Pions from Deuterium
The photoproduction of charged pions from deuterium has been studied using a monochromatic'' gamma-ray beam of 292 sintering time 8 Mev. The energy spectra of both posi-tive and negative pions at the laboratory angle of 120 were determined and both agreed within experimental error with tha...

| description | The photoproduction of charged pions from deuterium has been studied using a monochromatic'' gamma-ray beam of 292 sintering time 8 Mev. The energy spectra of both posi-tive and negative pions at the laboratory angle of 120 were determined and both agreed within experimental error with that predicted by the theory of Lax and Feshbach. The negative-to-positive ratio at 120 was 1.07 sintering time 0.16, and within experimental error, was independent of meson energy. At an angle of 73 the ratio was 0.90 sintering time 0.23 for 98.7 Mev mesons. The measured negative-to-positive ratio disagrees both with the simple classical picture of Brueckner and the phenomenological theory of Watson. Some results on the ratio using a bremsstrahlung beam are given. (auth) |
