Investigation of X-ray natural circular dichroism in a CsCuCl3 single crystal: Theory and experiment

X-ray natural circular dichroism in the near-Cu K edge in a CsCuCl 3 single crystal, caused by dipole-quadrupole ( E 1 E 2) transitions between electronic states of different parity, has been experimentally and theoretically investigated. Numerical simulation of the experimental X-ray absorption spe...

More Information
Summary:X-ray natural circular dichroism in the near-Cu K edge in a CsCuCl 3 single crystal, caused by dipole-quadrupole ( E 1 E 2) 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.
