The structure of dense particle clouds surrounding ablating hydrogen isotope pellets is investigated with primary attention to the B-perpendicular expansion and deceleration dynamics. The results show that collisional coupling between neutral and ionized components is strong enough to change the initially spherically symmetric expansion of the neutral particles to a field-aligned flow pattern, in agreement with the experimentally observed elongated radiation emission patterns of the excited neutral atoms. Calculated clouds parameters are compared with measured data and with results stemming from comparative calculations.
