Absolute Measurement of Ionization Cross Sections in Collisions Between Rydberg Sodium Atoms.
Absolute ionization cross sections have been determined for collisions between sodium atoms in laser-selected Ryberg states. Measurements were made in a thermal-energy self -colliding beam for n = 26-29 D states. The cross sections have been found to be roughly fifty times geometric and show fair agreement with a recent classical trajectory Monte Carlo calculation but differ greatly from an earlier indirect measurement.
