Collisions of multiply charged solar wind ions with cometary molecules lead to infrared and far ultraviolet photon emissions [1]. As it was shown in previous work by [2-4] the resulting spectra of the emission yields have astrophysical implications and can be used for testing such properties of the solar wind as velocity, density, and chemical composition. In present work experimental data for the state selective electron capture by He²⁺ ions from water molecules are presented. Three complimentary experimental techniques: Translational Energy Spectroscopy, Photon Emission Spectroscopy and Fragment Ion Spectroscopy were used for measuring state selective electron capture cross sections [5]. Experimental data are compared to the theoretical calculations. Theoretical calculations were carried out using basis approach which is proven to provide a good agreement with the experimental measurements.
