heal.abstract	We measured the momentum dependency of the energy and width of the π plasmon in graphite, using high-resolution electron energy-loss spectroscopy. For low momentum transfer the energy dispersion is positive and for high momentum transfer it becomes constant, in contrast with previous transmission electron energy-loss measurements. The width dispersion is negative for low momentum transfer and positive for higher momentum	en
