The losses of electrons due to the processes of dissociative attachment to the neutral water molecules in the course of solar wind stagnation near comets like Halley comet result in a sharp decrease of electron temperature at a definite density of neutral gas from 2 eV to about 0.1 eV. This is the reason of formation of a sharp plasma boundary between the solar wind loaded by cometary ions and a stagnated cometary plasma above the contact surface, finding itself in photoionization equilibrium. Another consequence of these processes is the appearance of a large amount of negative ions with density of the order of electron density above this boundary, because closer to the cometary nucleus their density is negligible.
