EXAFS Determination of Zero-Point Anharmonicity in Solid Iodine

Abstract

Interatomic Potential for an Isolated Bond

Interatomic Potentials

EXAFS

EXAFS are Absorption Oscillations At Energies Above “Edge”

EXAFS is caused by interference between outgoing and backscattered photoelectron waves

EXAFS Cumulant Expansion

Methodology

Iodine at 220K
