N2 - The vibrational and electronic predissociation of the NeI2(E ) complexes has been studied for the first time using two-step laser excitation of the complexes formed in a supersonic molecular beam. The I2(E → D → X β1g → A1u, γ1u → a1g and δ2u → 2g(aa)) luminescence have been observed, and luminescence spectra of these transitions have been measured. We have determined binding energies of the NeI2(E, v E = 0-6, n E) complexes, vibrational populations of the E, D, and β states as well as branching ratios of the vibrational and electronic predissociation channels. It has been shown that binding energies of the RgI2(E, v E = 0, n E = 0) vdW complexes, Rg = He-Kr, are directly proportional to the Rg polarizabilities. PESs for NeI2(B, E) complexes have been constructed in a diatomics-in-molecule model. These surfaces describe adequately excitation spectra of the luminescence observed. The NeI2(E, v E, n E) complex electronic predissociation is described in the framework of the energy gap model.
