X-Rays (Organic Synthesis)
An X-ray is a form of electromagnetic radiation having a wavelength in the range of 0.01–10 nm, corresponding to energies in the range 120 eV–120 keV. These ranges are intermediate between vacuum ultraviolet light and gamma rays. Neutron stars, white dwarf stars, supernova remnants, cluster of galaxies, and black holes in active galaxy nuclei are sources of intense X-rays. X-rays and cosmic rays may be implicated in the prebiotic formation of organic compounds in the primitive Earth atmosphere.
From the standpoint of astrobiology, it has been proposed that electromagnetic radiation or cosmic rays are the effective energy sources for synthesizing the precursors of terrestrial organic compounds in the primitive Earth environment. Experiments designed to verify this hypothesis have been conducted using photon beams from synchrotron-radiation light sources and proton, ion, or electron beams from high-energy particle accelerators, simulating electromagnetic radiation and...
