Abstract
High-precision measurements of the $^{241}$Am(n,2n)$^{240}$Am reaction have been performed with neutron energies from 7.6 to 14.5 MeV. The monoenergetic neutron beams were produced via the $^{2}$H(d,n)$^{3}$He reaction using the 10 MV Tandem accelerator at TUNL. The radioactive targets consisted of 1mg highly-enriched $^{241}$Am, sandwiched between three different thin monitor foils. They were irradiated with a neutron flux of 3x10$^{7}$ n cm$^{-2}$s$^{-1}$. After each irradiation the induced activity in the targets and monitors was measured off-line with 60{\%} HPGe detectors. Our neutron induced cross sections will be compared with recent literature results and statistical model calculations.
