Abstract
The results of our earlier charge-exchange measurements in ${\mathrm{He}}^{+}$ + He collisions are extended down to scattering angles of 0.05\ifmmode^\circ\else\textdegree\fi{} at energies of 1.00, 2.00, and 3.00 keV. The structure in the probability of charge exchange as a function of angle is clearly demonstrated. At very small angles the incident beam interferes with scattering measurements, and a technique for studying structure in this angular region is described.
