An analytical distribution function is developed that describes the influence of a light ion component on the explosion of a spherically symmetric, charged cluster composed of two species, when the cluster is irradiated by an ultrashort, intense laser pulse. It is shown that the energy distribution of light ions can be used for diagnostics of the initial density profile of the plasma cluster. The evolution of the energy distribution of light ions is investigated as a function of their number in the cluster. It is possible to create a quasimonoenergetic distribution of the light ions at a specific proportion of the light ions and the degree of ionization of the heavier ion component. Analytical calculations of the explosion of 50 nm water clusters exposed by ultrashort and intense laser pulses are in good agreement with Particle-In-Cell simulations.
