The methods employed and the results obtained from measurements and calculations of the detection efficiency for the neutron detectors used at Triangle Universities Nuclear Laboratory TUNL in the simultaneous determination of the S-1(0) neutron-neutron and neutron-proton scattering lengths a(nn) and a(np) respectively, are described. Typical values for the detector efficiency were 0.3. Very good agreement between the different experimental methods and between data and calculation has been obtained in the neutron energy range below E-n = 13 MeV. (c) 2008 Elsevier B.V.
