Experimental differential cross sections for the optical collision process Na(3s)2S + Xe + hν → Na(3p)2P + Xe are presented. By comparison with the results of accurate quantum calculations, the observed oscillatory structure is used to investigate the X2Σ and B2Σ potential curves of the NaXe van der Waals molecule. The repulsive branches of both curves are probed in addition to the binding minimum of the ground state. A value of 92 cm-1 is obtained for the dissociation energy.
