Solid film of racemic amino acid (DL-alanine) was irradiated by circularly polarized Lyman-alpha light in UVSOR-III, to investigate a cosmic scenario of the origin of the homochirality of terrestrial biomolecules. Optical activity emergence was clearly observed in the circular dichroism spectrum measured at HiSOR. Effects of magnetic field application is also discussed.
