Cross-calibration of atomic pressure sensors and deviation from quantum diffractive collision universality for light particles

Cross-calibration of atomic pressure sensors and deviation from quantum diffractive collision universality for light particles

The room-temperature, velocity-averaged, total cross section for atom–atom and atom–molecule collisions can be approximated using a universal function depending only on the magnitude of the leading order dispersion coefficient, C _6 . This feature of the total cross section together with the univers...
