Measurements of the low-energy electronic structure in ${\mathrm{Gd}}_{2}{\mathrm{PdSi}}_{3}$ and ${\mathrm{Tb}}_{2}{\mathrm{PdSi}}_{3}$ by means of angle-resolved photoelectron spectroscopy reveal a Fermi surface consisting of an electron barrel at the $\ensuremath{\Gamma}$ point surrounded by spindle-shaped electron pockets originating from the same band. The calculated momentum-dependent RKKY coupling strength is peaked at the $\frac{1}{2}\ensuremath{\Gamma}K$ …
