Parameters of the Lu¹⁷⁶ Neutron Resonance at 0.142 ev

The total cross section of Lu¹⁷⁶ was measured over the range of neutron energies from 0.02 to 0.25 ev. The data were taken with a sample enriched to 70.2% in Lu¹⁷⁶. The resonance at 0.142 ev in Lu¹⁷⁶ was fitted to a Breit-Wigner single-level formula by the method of shape analysis. Parameters are presented for computing the activation cross section as a function of neutron energy over the region of measurement.
