Absorption of circularly polarized gamma-radiation in L- and D-amino acids

No difference within the experimental error (approximately 10(-3)) was observed in the absorption of right- and left-circularly polarized gamma-radiation in L- and D-tryptophan and tyrosine. For the measurements the 14.4 keV transition of 57Fe was used and the analysis of circularly polarized gamma-radiation was performed by Mössbauer method.
