  We discuss in detail the dependence of the Gallium Anomaly on the detection
cross section. We provide updated values of the size of the Gallium Anomaly and
find that its significance is larger than about $5\sigma$ for all the detection
cross section models. We discuss the dependence of the Gallium Anomaly on the
assumed value of the half life of ${}^{71}\text{Ge}$, which determines the
cross sections of the transitions from the ground state of ${}^{71}\text{Ga}$
to the ground state of ${}^{71}\text{Ge}$. We show that a value of the
${}^{71}\text{Ge}$ half life which is larger than the standard one can reduce
or even solve the Gallium Anomaly. Considering the short-baseline neutrino
oscillation interpretation of the Gallium Anomaly, we show that a value of the
${}^{71}\text{Ge}$ half life which is larger than the standard one can reduce
the tension with the results of other experiments. Since the standard value of
the ${}^{71}\text{Ge}$ half life was measured in 1985, we advocate the
importance of new measurements with modern technique and apparatus for a better
assessment of the Gallium Anomaly.
