► We provide a new constraint for the relative scintillation efficiency of liquid xenon. ► For this purpose, we discuss electronic and nuclear stopping powers and recombination. ► We point out the correlation between scintillation efficiency and ionization yield. ► In conclusion, the relative scintillation efficiency cannot decrease at low energies.
