n(k) Structure and Matrix Elements in Photoemission: Results from Insulating Ca_2CuO_2Cl_2
F. Ronning, C. Kim, K. M. Shen +5
The photon energy dependence of angle-resolved photoemission data on Ca_2CuO_2Cl_2 is presented, and the role of the matrix element is investigated. It is shown that despite strong…

Selection Rules for Resonant Inelastic X-Ray Scattering from Tetragonal Copper-Oxides
P. Abbamonte, C. A. Burns, E. D. Isaacs +3
We demonstrate the utility of point group representation theory for symmetry analysis in resonant inelastic x-ray scattering. From its polarization-dependence, we show that a 5 eV…
