Nondipole Photoemission from Chiral Enantiomers of Camphor

POSTER

Abstract

K-shell photoemission from the carbonyl carbon in the chiral molecule camphor has been studied in the region just above the core-shell ionization threshold. Differences between angular distributions of emitted photoelectrons from the two enantiomers are attributed to the influence of chirality combined with nondipole effects in the photoemission process, despite the fact the measurements were taken using \textit{linearly polarized} x-rays. The results suggest the possibility of a new form of linear dichroism.
