Abstract
The objective of this work is to measure the stopping power of Al and Au for α particles and analyze the agreement with theoretical models. The measurements were performed using the transmission method with a silicon detector in vacuum, employing two radioactive sources: a sealed 241Am and an unsealed triple-nuclide source (233U, 239+240Pu, 241Am), covering an energy range from 4.3 MeV to 5.3 MeV. Special attention was paid to the target characterization, determining the
foil thicknesses to reduce the large uncertainties associated with nominal manufacturer specifications.
The results for both materials show excellent agreement with the ASTAR database and confirm the necessity of low-energy corrections to the Bethe formula for high-atomic-number materials
