The total neutron cross section of 182Ta has been measured from 0.01 to 1000 eV using the MTR fast chopper. The observed total neutron cross section at 0.0253 eV is 8200 ± 600 b. Parameters of individual resonances below 30 eV and average parameters at higher energies give a resonance absorption integral of 943 ± 50 b and a neutron s-wave strength function of (1 ± 0.1) × 10−4 (eV) 1/2. The possible use of 182Ta as a neutron temperature monitor is discussed.
