Va. Grinchuk et al., DISPERSION PROPERTIES OF THE SCATTERING OF SODIUM ATOMS IN A STRONG-FIELD OF SHORT COUNTERPROPAGATING LASER-PULSES, JETP letters, 57(9), 1993, pp. 548-551
Experimental results on the scattering of a beam of sodium atoms in a
strong field of short counterpropagating pulses of resonant laser ligh
t are presented. The scattering amplitude oscillates nonmonotonically
with frequencies of the order of 10 GHz as a function of the detuning
from resonance. In general, the scattering diagram is asymmetric relat
ive to the direction of propagation of the undisturbed beam, and the s
ign of the asymmetry is an oscillating function of the detuning.
