Measurement of parity violation in the photodisintegration of deuterium and in the production of bremsstrahlung on tantalum

The circular polarization dependent component of the total cross section for photodisintegration of deuterium has been measured: (2.7 ± 2.8) x 10-6 for bremsstrahlung with an end point of 4.1 MeV and (7.7 ± 5.3) x 10-6 for an end point of 3.2 MeV. The helicity-dependent component of the total cross section for the production of bremsstrahlung on tantalum by longitudinally polarized electrons has been measured: (0.63 ± 0.70) x 10-6 for an electron energy of 4.1 MeV and (3.1 ± 1.5) x 10-6 at 3.2 MeV. All measurements are in agreement with theoretical predictions for these processes. (12 refs., 3 tabs., 3 figs.)
