Abstract
Triple-axis neutron spectroscopy has been used to study the high energy magnetic excitations of iron and nickel. Excitations of energies up to 300 meV have been observed. The experimental results demonstrate clear evidence for interactions between spin-waves and single particle excitations as well as the existence of "multiple branches" of excitations
