The electronic stopping power and the energy loss straggling of low velocity H‐, He‐, Li‐ and Be‐like ions in the degenerate electron gas were calculated. The Hartree‐Fock‐Slater description of the ion and the dielectric function method were used. The stopping and straggling effective charges Z eff of an ion were analysed. They are found to differ with each other and to depend on the electron gas density r s , on the ion atomic number Z i and on N i , the number of electrons carried by the ion.
