Abstract
We present the first direct measurements of the velocity dependence of
the average force and diffusion constant for the metastable neon atoms
in a one-dimensional σ+σ- laser
cooling configuration. Force and diffusion are determined, respectively,
from the deflection and broadening of a highly collimated atomic beam by
its interaction with a pair of counter-running laser beams. The
interaction time is much shorter than the characteristic damping time of
the cooling process. The resulted force and diffusion measurements are
compared with the results of both semiclassical and quantum Monte Carlo
calculations.
