Outline of Final Research Achievements

Quantum Electrodynamics (QED) is considered to be one of established theories but there is unverified phenomena that are predicted by QED. One of such phenomena is interactions between photon and photon. These phenomena have not been well studied experimentally and theoretically. One of such interactions is Delbruck scattering, which has remarkable feature that its cross section is much larger than those of other photon-photon interactions but its theoretical calculation is more complex rather than the others. We have proposed a new method to measure selectively the amplitude of Delbruck scattering using linearly polarized gamma-rays. To perform it, we developped a laser Compton scattering gamma-ray beam with an upper energy of 1 MeV and measured its scattering at the UVSOR radiation facility.

Academic Significance and Societal Importance of the Research Achievements

量子電磁力学理論では、光子と光子が散乱などの反応を起こすことが予想されている。このような現象の一つに、デルブリュック散乱と呼ばれる現象がある。このデルブリュック散乱は量子電磁力学理論をさらに発展させるために重要であり20世紀より実験が進められていたが行き詰っていた。そこで、直線偏光したγ線を使うことで実験を行う新しい手法を提案し、そのためにγ線ビームを作りデルブリュック散乱の実験を行った。
