The turbulence produced by lower hybrid waves, during interaction of solar wind with the cometary pick‐up ions, leads to stochastic acceleration of these ions. The resulting energies of the cometary ions, calculated on the assumption that the entire turbulent electric field is used up for accelerating particles, are much larger compared to the recently observed energies of water‐group ions in the vicinity of comets Halley as well as Giacobini‐Zinner. Accounting for the fact that only a fraction of the field would lead to acceleration and the rest to heating, lower hybrid waves seem to be a potential source for the observed energetic cometary ions.
