Abstract :
A first proof of principal experiment of measuring neutron capture cross sections of radioactive isotopes was performed on 171Tm which has a half life of 1.92 years. This isotope was chosen for its ease of production and its radiation properties. The experiment was done at an 8 meter irradiation station at LANSCE using the pulse height weighting technique. A complemental activation measurement at FZK as well as a theoretical estimation indicated a significant background component above 1 keV neutron energy during the experiment at LANSCE.
