Abstract Number of nucleons scaling for elliptic flows of light charged particles (LCPs) (A ≤4) is studied for 40 and 200 MeV/A¹⁹⁷Au+¹⁹⁷Au collisions at impact parameter of 6–12 fm by the isospin-dependent quantum molecular dynamics model. The transverse-momentum-dependent ratios of v₄/v₂² and v₃/(v₁v₂) are also found to be scaled for different LCPs from the two different energy collisions, and approximately equal to 0.5 and 0.55, respectively. All the above description can be seen as the result of nucleonic coalescence mechanism.
