Abstract

Experiments were performed to measure the thickness of 10B and 11B targets using the α-transmission method. These targets were prepared at INFN. A 241Am source provided α particles of 5.486 MeV energy. The results were compared with the supplier’s values, showing a good agreement in thickness for the 11B target, while the results for the 10B target were reasonable within the uncertainty range.
