In a temperature-controlled neon discharge cell under a magnetic field up to 7 T, a linearly polarized laser pulse has produced polarized neon atoms (atomic alignment) on the 2p 2 (in the Paschen notation) level from the 1s 3 level. The subsequent fluorescence to the 1s 2 level was observed with its polarized components being resolved. The disalignment rate coefficients of the 2p 2 atom due to neon atom collisions were determined at the temperature of 77 and 300 K. At each temperature, the rate coefficient shows no dependence on the magnetic field within the experimental accuracy.
