Abstract
The kinetic-energy change in electron-capture collisions between and He or Ne in the collision energy range 0.2-2.4 keV has been observed with sufficient resolution to separate all possible final states. These processes were modeled in terms of both a curve-crossing and a noncrossing mechanism. The results suggest that the observed transitions occur at an intermediate internuclear separation, , and that the noncrossing mechanism is important when an appropriate crossing does not occur within this range.
