Baumann, Michael Meyer, Manuel Harder, Zhong Yin, Olle Björneholm, Joseph Nordgren, Stephan Fritzsche, Victor Kimberg, Jan-Erik Rubensson, and Faris Gel’mukhanov Interference between scattering channels is observed in resonant inelastic x-ray scattering (RIXS) at the Ne $K$ threshold. Final states with $|2{p}^{−1}np⟩$ as the main configuration are populated via $|1{s}^{−1}{n}^{′}p⟩$ resonances, where large-amplitude one-electron (${n}^{′}=n$) channels interf… [Phys. Rev.
