French tests appear to have found traces of chemicals linked to the nerve gas VX on Iraqi warheads, according to several weapons experts who said this would confirm earlier American test results.

Sx is the sticking coeﬃcient (assumed to be 0.3 for all species), a is the grain radius, ng is the number density of the grains, vx is the gas phase velocity of species x and nx is the number density of x.

The freeze-out rate is where Sx is the sticking coeﬃcient (assumed to be 0.3 for H atoms and 1 for all other species; Table 3), vx is the gas-phase velocity of species x, and nx is the gas-phase number density of x.

As a candidate of the photosphere, we take an iso-density surface, and plot the horizontal velocity components, Vx and Vy , of the gas on the Vx − Vy plane, i.e.
