摘要：

Proton-proton bremsstrahlung cross sections have been measured at 389 MeV incident energy. A two-arm spectrometer and a liquid hydrogen target system have been used to measure the proton-proton bremsstrahlung events with small background. At the present kinematical conditions, an enhancement of the cross sections due to the Delta current contribution is predicted. The measured cross sections are larger than the theoretical predictions including the a current contribution.
