✦ Synopsis
We have revisited photoassociative ionization (PAI) in a cold sample of Na atoms. A two-color experiment was performed in a magneto-optical trap through the addition of a probe laser. The observation of a marked change in the PAI rate for a definite frequency range can be attributed to the influence of repulsive levels and a possible avoided crossing between longrange molecular levels. ln(Ions rate) 3.5 4.0 2.5 3.
