(a) Integral cross sections Q, measured as a function of the collision velocity v19, plotted as Qv2/5 to emphasize the “glory” interference pattern, compared with calculations, carried out within the semi-classical JWKB approximation21, by the present optical potentials for Ne* (3P2,0) atoms scattered by N2. (b) The long-range behavior of isotropic (spherically averaged) real part of the optical potential in the entrance channels, compared with that of ref.21.
