The stopping power of dense electron plasmas is determined using a simplified version of the method of moments based on some interpolation formulas for the sum rules of the loss function. The energy losses of ions are evaluated with various projectile charges moving in a plasma at different values of the coupling and degeneracy parameters. The losses of slowly moving charged particles are closely examined. The results obtained are compared with those of some alternative approaches and the particle‐in‐cell (PIC) simulation data.
