Radioactive Isotopes of Ag and Cd

Abstract

${\mathrm{Ag}}^{105}$: An activity with a half-life of 40 days, has been produced by the following reactions: $\mathrm{Rh}(\ensuremath{\alpha},2n)$, $\mathrm{Pd}(\ensuremath{\alpha},p)$, $\mathrm{Pd}(d,2n)$ and $\mathrm{Pd}(p,n)$. This activity decays by $K$-electron capture only.${\mathrm{Ag}}^{110}$: An activity with a half-life of 270 days previously reported as 225 days, has been produced by $\mathrm{Pd}(d,2n)$ and ${\mathrm{Ag}}^{109}(d,p)$ reactions.${\mathrm{Cd}}^{105}$: An activity with a half-life of 57 minutes has been produced by the $\mathrm{Cd}(n,2n)$ and $\mathrm{Pd}(\ensuremath{\alpha},n)$ reactions. Decay is accompanied by a 1.5-Mev positron and $K$-capture.${\mathrm{Cd}}^{109}$: An activity with a half-life of 470 days, previously reported as 330 days, has been produced by the $\mathrm{Ag}(d,2n)$ and $\mathrm{Pd}(\ensuremath{\alpha},n)$ reactions.
