We have measured electron-circularly-dichroic asymmetries when longitudinally-polarized (chiral) electrons are scattered quasi-elastically by chiral halocamphor molecules: 3-bromocamphor (c10h15bro), 3-iodocamphor (c10h15io), and 10-iodocamphor. The proposed dynamic origins of these asymmetries are considered in terms of three classical models related to mott scattering, target electron.

Electron transmission through chiral molecules induced by circularly polarized light can be very different for mirror-image structures, a peculiar fact given that the electronic energy spectra of the systems are identical. We propose that this asymmetry--as large as 10% for resonant transport--arises from different dynamical responses of the mirrored structures to coherent excitation.
