We report on possible effects of quantum-mechanical interferences between gravitational forces and the nucleus-nucleus Coulomb interaction. We show that, although very small, these effects could be measured on using low-energy scattering between identical heavy nuclei. For the system ${}^{208}\mathrm{Pb}{+}^{208}\mathrm{Pb}{(E}_L=5\mathrm{}\mathrm{MeV})$. The angular precision needed would be about $0.001°$.
