Thermal (n, γ) cross section and resonance integral of ¹⁷¹Tm

NUCLEAR REACTIONS ¹⁷¹Tm(n, γ), E=thermal; measured Eγ, Iγ, thermal and epithermal neutron fluence, σ, and resonance integral using activation technique at Triga reactor facility in Mainz. Comparison with previous experimental values, and with data in evaluated libraries. Relevance to s process in thermally pulsing asymptotic giant branch (TP-AGB) stars.

66.7-keV γ-line intensity of ¹⁷¹Tm determined via neutron activation

RADIOACTIVITY ¹⁷¹Er(β^-)[from ¹⁷⁰Er(n, γ), E=thermal]; ¹⁷¹Tm(β^-)[from ¹⁷¹Er β^- decay]; measured Eγ, Iγ, E(x rays), I(x rays), precise intensity of the 66.7-keV γ ray from the decay of ¹⁷¹Tm; deduced number of ¹⁷¹Er and ¹⁷¹Tm atoms produced in reactor irradiation. Relevance to ¹⁷¹Tm neutron capture cross section, and s process in thermally pulsing asymptotic giant branch stars.
