Asymmetrical Interactions of Positrons With D. L. DL-Leucines

The question on the origin of the optically active molecules in nature has puzzled scientists for a long time. Shortly after Lee and Yang discovered the parity nonconservation in the weak interactions, Vester and Ulbricht suggested that this phenomenon could explain the origin of chirality of biological molecules. They proposed a transfer of asymmetry from the elementary particle level to the molecular level via the mechanism: β-decay→longitudinally
