PARTICLE DISTRIBUTION FUNCTIONS  

DÉFINITION

  • A characterization of the density of particles located at a given point in phase space (a combination of either velocity or position coordinates) at a given time. The velocity-space distribution function gives the number of particles with a particular velocity; the position-space distribution function is synonymous with the particle density in position-space. Different combinations of position and spatial coordinates are useful in different problems.
