Abstract

We evaluate the effects of gamma-ray from decay of aluminium-26 as an energy source for the formation of organic matter, specially amino acids during aqueous alteration in early planetesimals. We report experiments of gamma-ray irradiation to solutions containing formaldehyde and ammonia. The results suggest that amino acid precursors were formed by the gamma-ray irradiation to the formaldehyde and ammonia water solutions, and the reaction mechanisms could be different from those of heating.
