Angular distributions and total cross sections for D formation from interaction of D+ and D0 with cesium

Abstract
Absolute differential scattering cross sections have been determined for single and double electron-capture collisions of 0.5- to 2.5-keV D+ and D0 in Cs vapor. Integration of the differential cross section over the scattering angles yielded the total electron-capture cross sections. Angular distributions were peaked in the forward direction, and the angular width increased as the particle energy decreased. Cross sections for both single and double capture processes decreased with increasing energy.
