Low-energy collisions ofD+with D andHe2+with He

Quantum-mechanical calculations for differential cross sections and various transport cross sections describing the thermal-energy collisions of ${\mathrm{D}}^{+}$ with D and ${\mathrm{He}}^{2+}$ with He are presented. Lowest-order Viehland-Mason theory is used to calculate mobility of ${\mathrm{D}}^{+}$ in D. The zero-field mobility at 77, 303, and 10000 K is, in units of ${\mathrm{cm}}^2$ ${\mathrm{V}}^{-1\mathrm{}}$ ${\mathrm{s}}^{-1\mathrm{}}$, 10.5, 7.0, and 2.1, respectively.
