John Vinson (Fed)

Physicist

My primary interest is first-principles spectroscopy, focusing on near-edge x-ray absorption, emission, and resonant inelastic x-ray scattering. Computational spectroscopy provides a direct connection between the structure of a material on the atomic scale to the spectra that can be observed in experiments. I work with groups inside and outside of NIST to help them interpret and understand their measurements. I am also the lead developer of the spectroscopy code OCEAN

If you are a postdoctoral candidate, NIST participates in a centrally-funded postdoc program run through the National Research Council of the National Academies. Positions are open to US citizens, and application deadlines are twice a year on Feb 1 and Aug 1. For more information, click here, visit sites.nationalacademies.org/pga/rap, or send me an email.

Non-resonant Two-photon X-ray Absorption in Cu

Author(s)
Joshua Kas, John Rehr, Joachim Stöhr, John Vinson
We present a real-space Green's function theory and calculations of two-photon x-ray absorption (TPA). Our focus is on nonresonant K-shell TPA in metallic Cu
