Neutron capture cross sections of ¹⁷⁸Hf leading to ¹⁷⁹Hf^m2

NUCLEAR REACTIONS ¹⁷⁸Hf(n, γ)^179mHf, E=epithermal; measured Eγ, Iγ, σ, resonance integral, half-life of ^179mHf decay using HPGe detector for γ detection using TRIGA reactor at Oregon State University. Systematics of neutron capture σ for ⁹²Mo, ¹⁷⁷Hf, ¹⁷⁸Hf, ¹⁸⁹Os targets leading to high-spin states in product nuclei. Comparison with previous experimental results.

RADIOACTIVITY ^179mHf(IT)[from ¹⁷⁸Hf(n, γ), E=epithermal]; measured Eγ, Iγ, half-life of ^179mHf decay. ¹⁷⁹Hf; deduced high-spin levels, J, π. ¹⁸¹Hf(β^-)[from ¹⁸⁰Hf(n, γ), E=thermal]; ¹⁷⁵Hf(EC)[from ¹⁷⁴Hf(n, γ), E=thermal]; measured Eγ, Iγ. ¹⁷⁵Lu, ¹⁸¹Ta; deduced levels. Comparison with evaluated data in the ENSDF database, and with previous experimental results.
