Alignment relaxation of the Ne∗(2p5 3p; 2pi [J1]) atoms (where i 2, 5, 7 or 10) induced by collisions with He atoms in glow discharges at 77 K < T < 1,000 K are reported. Close-coupling many-channel quantum calculations using a model potential for the Ne∗(2p5 3p)-He system are compared with measurements of the alignment relaxation using the LIFS technique and the Hanle effect. The addition of the dipole polarization potential of the Ne∗(2pi [J1]) atoms to the spin-orbit coupling and the electrostatic interaction between Ne∗ and He atoms leads to good agreement between theory and experiment.
