Abstract
We present the elastic and charge exchange cross sections for slow (meV)H+ + D(1s) collisions based upon a recently formulated adiabaticrepresentation. This representation avoids many of the usual`translational factor' issues, and those that remain have no significanteffect for scattering in the n = 1 manifold. The cross sections areconverged at the 1% level. The various Feshbach and shape resonancesthat form in the isotopic gap and in the charge transfer region areidentified and compared with previous work. An exact analyticalexpression for the ratio of H+ + D(1s) and D+ + H(1s) chargeexchange cross sections suitable for astrophysical simulations ispresented.
