In a photoassociation process, two colliding cold cesium atoms absorb one photon to form an ultracold molecule, electronically excited in a well defined ro-vibration level. Because of the small initial kinetic energy of the free atoms, the photoassociation is resonant and permits high resolution spectroscopy of long-range states. We report spectra for states correlated to the excitated limit 6S+6P. The 1u (6S+6P3/2) state is a pure long-range molecules. It hardly consists in a molecule, but rather in a pair of two atoms linked at 1,5 nm by the multipolar electrostatic interaction. The intensity modulation of spectral lines for a given vibrationnal progression reflects the nodal structure of the radial s-wave function of two ground state ato...
