Figure A08-m4bii1-F1: Polar differential cross section for chemi-ionization (CM system) at E_i=13.1 eV, calculated in semi-classical approximation with the potential parameters of Table A08-m5bi-T1 and the coupling parameters H₁₂= 0.065 eV and H_rot  eV s.
(a) Differential cross section with complete interference structure, calculated with the lowest-order stationary-phase approximation. The region of the classical rainbow angle _cl,rb has been omitted.
(b) Differential cross section calculated with the stationary-phase approximation and uniform rainbow approximation showing separated the long-wavelength interference structures due to a + c (65,full curve), b + c (65250, full curve) and d + e ( 0 2300, dashed curve) interferences.
(c) Full bars indicate the measured maxima of the interference structure on the differential cross section due to net-attractive scattering. Dashed bars indicate the maxima due to net-repulsive scattering. The complete measured cross section curve at E_r =13.1 eV is given in Fig. A08-m4bi1-F1.
