Abstract

This paper discusses mass spectral analysis of the rate of formation of positive and negative cluster ions on the surface of the laboratory modeled comet nucleus under the influence of corpuscular particles of solar wind. The method of proportionality of emission coefficients is used in calculations. From the experimental data obtained to determine the rate of formation of cluster ions, it follows that on the surface layer of ice cometary nuclei under the action of corpuscular solar fluxes and cosmic rays, ion-molecular clusters of opposite signs of a charge of the kind H+(H2O) and OH-(H2O). The rate of formation of negative clusters has a quantitative advantage over positive ones.

Keywords:

comets, ion clusters, ion-molecular clusters, proportionality of emission coefficients, spray ice, mass spectral method, solar wind
