β-decay feeding intensity distributions for ^{103, 104m}Nb

RADIOACTIVITY ^103,104mNb(β^-)[from ⁹Be(¹²⁴Sn, X), E not given, followed by separation of fragments using A1900 separator at NSCL-MSU]; measured reaction products and particle identification plot from ⁹Be(¹²⁴Sn, X), Eγ, Iγ, total absorption gamma spectra from the decays of ¹⁰³Nb and ^104mNb using Summing NaI(Tl) (SuN) detector at the NSCL-MSU; deduced Iβ feedings to levels in ¹⁰³Mo and ¹⁰⁴Mo, cumulative B(GT) values. Comparison to predictions of quasiparticle random-phase approximation (QRPA) model. Relevance to antineutrino studies of nuclear reactors, and astrophysical r process.
