Popis: | X-ray natural circular dichroism in the near-Cu K edge in a CsCuCl3 single crystal, caused by dipole-quadrupole (E1E2) transitions between electronic states of different parity, has been experimentally and theoretically investigated. Numerical simulation of the experimental X-ray absorption spectrum and circular dichroism has been performed. It is established that a circular dichroism signal is observed in the pre-edge spectral region; therefore, it is mainly due to the localized electronic p-d states. |
