Abstract
The free neutron cross section of Silicone and Lead has been determined to (2.022 ± 0.003) barns and (10.58 ± 0.03) barns respectively and the incoherent cross section of the same elements to (15 ± 1.3) · 10−3 barns and (15 ± 15) · 10−3 barns respectively. From these results the coherent cross sections have been calculated under consideration of various correction terms to (2.153 ± 0.005) barns and (10.65 ± 0.05) barns.
