Total absorption study of the β decay of ^{102, 104, 105}Tc

RADIOACTIVITY ^102,104,105Tc(β^-)[from U(p, F), E=30, 50 MeV followed by mass separation]; measured Eγ, Iγ using the Total Absorption Gamma Spectrometer (TAGS) and JYFLTRAP Penning trap at IGISOL, Jyvaskyla facility; deduced β feedings to levels in ^102,104,105Ru, β-strength distributions, Gamow-Teller strengths, average β and γ energies, effects on decay heat calculations. Comparison of deduced β feedings with those from high-resolution γ-ray measurements. Comparison of Gamow-Teller strengths with VAMPIR model calculations. Relevance to decay heat calculations in nuclear reactors.

NUCLEAR REACTIONS U(p, F)¹⁰²Mo/¹⁰²Tc/¹⁰²Ru/¹⁰⁴Tc/¹⁰⁵Nb/ ¹⁰⁵Mo/¹⁰⁵Tc/¹⁰⁵Ru, E=30, 50 MeV; measured yields using JYFLRTRAP Penning trap at IGISOL, Jyvaskyla facility.
