Query: Decay Spectroscopy of $^{129}$Cd   Excited states of $^{129}$In populated following the $\beta$-decay of
$^{129}$Cd were experimentally studied with the GRIFFIN spectrometer at the
ISAC facility of TRIUMF, Canada. A 480-MeV proton beam was impinged on a
uranium carbide target and $^{129}$Cd was extracted using the Ion Guide Laser
Ion Source (IG-LIS). $\beta$- and $\gamma$-rays following the decay of
$^{129}$Cd were detected with the GRIFFIN spectrometer comprising the plastic
scintillator SCEPTAR and 16 high-purity germanium (HPGe) clover-type detectors.
%, along with the $\beta$-particles were detected with SCEPTAR. From the
$\beta$-$\gamma$-$\gamma$ coincidence analysis, 32 new transitions and 7 new
excited states were established, expanding the previously known level scheme of
$^{129}$In. The $\log ft$ values deduced from the $\beta$-feeding intensities
suggest that some of the high-lying states were populated by the $\nu 0 g_{7/2}
\rightarrow \pi 0 g_{9/2}$ allowed Gamow-Teller (GT) transition, which
indicates that the allowed GT transition is more dominant in the $^{129}$Cd
decay than previously reported. Observation of fragmented Gamow-Teller
strengths is consistent with theoretical calculations.
