Cross-sections for elastic scattering of muonic hydrogen on helium nuclei, (hμ)_{1s} + He^{++}, where h and He^{++} stands for a hydrogen and a helium isotope nucleus, respectively, were calculated in the one-level adiabatic approximation for a range of collision energies from 0 to 50 eV. Bound states and energy levels of (hμHe)^{++} molecular ions were also calculated and compared with their Born-Oppenheimer counterparts. It is shown that adiabatic corrections are responsible for proper positions of the Ramsauer-Townsend minima in (hμ)_{1s}+He^{++} elastic scattering and, at the same time, they significantly influence bound states and energy levels of (Heμh)^{++} and (Heπh)^{++} ions. Calculations were performed in the frame of the phase-function method.
