Within the one-configuration molecular-orbital scheme, diabatic molecular states of the molecular ion HeD$sup +$ involved in the collisional process He$sup +$ + D are determined by the shielded diatomic orbitals (SDO's) method. These SDO's are exact solutions of the one-electron--two-center problem with an effective parametric potential. This potential, which preserves the separability in prolate spheroidal coordinates of the Schrodinger equation, is obtained by classical electrostatic considerations. Differential cross sections for the He$sup +$D colliding system are determined by a semiclassical collisional method. Good agreement is found with recent experimental results in the keV energy range.
