We investigated the production of the graphite contained in the soot of single-walled carbon nanotubes (SWCNTs) synthesized using the arc discharge method with a poorly graphitized carbon (PGC) rod in comparison to a graphite rod. A PGC rod was produ

A series of Kβ resonant inelastic X-ray scattering (RIXS) spectra of α-Fe2O3 is presented as two-dimensional RIXS maps and analyzed in terms of the Kramers–Heisenberg equation. Genuine lifetime-broadening-suppressed (LBS) spin-selected oscillator

Lifetime-broadening-suppressed X-ray absorption near-edge structures (LBS-XANES) spectra, where the resolution is not restricted by core-hole lifetime widths, have been measured at the Cu K-edge on the prototypical high- T c La 2− x Sr x CuO 4 ( x

Electron momentum profiles of the highest occupied molecular orbital (HOMO) of acetone have been measured under experimental conditions where a use of the plane-wave impulse approximation is justified. A double peak is observed in the experimental pr
