Effects of alignment and interference in resonant transfer and excitation for ${\mathrm{F}}^{6+}$ and ${\mathrm{O}}^{5+}$ collisions with ${\mathrm{H}}_2$ in 0° Auger measurements

We have renormalized our previously reported 0° cross sections for zero resonant transfer and excitation calculation using high-resolution Auger spectroscopy (RTEA), d${\mathrm{\sigma }}_{\mathrm{RTEA}}$(0°)/dΩ, obtained in 0.25–2-MeV/u collisions of ${\mathrm{F}}^{6+}$ and ${\mathrm{O}}^{5+}$ ions with ${\mathrm{H}}_2$ by normalizing to calculated binary-encounter electron yields rather than the usual Ne K Auger yields. The renormalized data are found to be in good agreement with recent angular-dependent impulse-approximation calculations of RTE, showing the importance of alignment and the small influence of interference between RTEA and elastic electron scattering for a 0° observation.
