# @kalika/xas

X-ray absorption spectroscopy for Kalika (Phase 124): muffin-tin potentials,
complex radial Schrodinger (Numerov) phase shifts and t-matrices, real-space
full multiple scattering XANES (free-electron propagator, FMS matrix inversion,
dipole/quadrupole cross-sections, cluster generation), edge types with XNLD/XMCD
sum rules and pre-edge analysis, EXAFS path expansion with Debye-Waller factors
and cumulants, k/R-space EXAFS fitting, and XAS processing (background, E0,
chi(k), Fourier transforms).
