Abstract

X-ray absorption and resonant inelastic x-ray scattering measurements are carried out on lithium nitrate LiNO3. Echoing previous studies on ammonium nitrate, the σ orbitals around the nitrogen atoms exhibit a large lifetime effect. Experimentally, this is manifest as an apparent weakening of the x-ray emission signal from these states, but a closer examination shows this to be due to extreme broadening. Using first-principles self-energy and Bethe-Salpeter equation calculations we show that this effect is due in part to short quasi-hole lifetimes for orbitals in the NOσ bonds.
