“…Furthermore, the low energy measurement results were in good agreement with the high energy one within the experimental error. The experimental data of Lee et al [3] are largely different from others measured data in the energy region below 0.5 eV.…”

“…Herdade et al (1973) [1] measured the total cross sections from 8.2 × 10 −4 eV to 0.13 eV using slow chopper with a nuclear reactor. Granada et al (1987) [2] obtained the total cross sections from 0.001 eV to 10 eV using an electron linear accelerator (LINAC) and seven 3 He proportional counters. Recently, Lee et al (2002) [3] measured the total cross sections from 0.01 eV to 100 eV at the Pohang Neutron Facility (PNF) using a LINAC to study the possibility to produce nuclear data at the PNF.…”

The neutron total cross sections of polyethylene have been measured in the energy region from 0.001 eV to 40 keV by the time-of-flight (TOF) method using the Kyoto University Institute for Integrated Radiation and Nuclear Science-Linear Accelerator (KURNS-LINAC). A 6 Li detector and a gas electron multiplier (GEM) detector have been used as a neutron detector, and the polyethylene plates of 0.31 and 0.20 cm thickness were employed for the neutron transmission measurement. The present results were compared with the previous results and the evaluated data in JENDL-4.0. In the energy region below 0.01 eV, the present results are in good agreement with the data measured by Herdade et al. (1973) and by Granada et al. (1987). On the other hand, the evaluated data in JENDL-4.0 are larger than all the measured data. In the energy region from 0.035 to 0.15 eV, the data measured by Granada et al. and the evaluated data in JENDL-4.0 are up to about 4~6% larger than the present results.
