Figure A08-m4bii1-F1: Polar differential cross section for chemi-ionization (CM
system) at Ei=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 Hrot
(a) Differential cross section with complete
interference structure, calculated with the lowest-order
stationary-phase approximation. The
region of the classical rainbow angle
(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 Er =13.1 eV is given in Fig. A08-m4bi1-F1.
