Abstract

We have searched for evidence of electron circular dichroism, the preferential transmission of longitudinally polarized electrons through a chiral medium, using stereoisomers of camphor. Such an effect was seen by Campbell and Farago in 1987 for 5 eV electrons. Within our detection limit (-- 0.02%) we have not observed asymmetric transmission at either an incident electron energy of 1 eV or 5 eV. In preparation for this inquiry, we also measured the total scattering cross section for camphor in the energy range 0.5-5 eV.
