9 results about "Radial distribution function" patented technology

In statistical mechanics, the radial distribution function, (or pair correlation function) g(r) in a system of particles (atoms, molecules, colloids, etc.), describes how density varies as a function of distance from a reference particle. If a given particle is taken to be at the origin O, and if ρ=N/V is the average number density of particles, then the local time-averaged density at a distance r from O is ρg(r).
