Abstract

In this paper, a high sensitive photoassociation spectroscopy based on modulated ultra-cold cesium atoms is reported. The cold cesium gas in the magneto-optical trap is illuminated by a photoassociation laser with red detuning 40 cm-1 below the 6S1/2+6P3/2 dissociation limit and photoassociation to the excited state ultra-cold molecules is observed. The rotationally bound levels of 0g- state are well resolved using the lock-in detection. The 0g-, 1g and 0u+ long range states which connect to this dissociation limit are measured. The long-range dipole–dipole interaction constants are determined through a fit of the experimental energy levels.
