Disintegration of 24-MinuteAg106

Abstract

The 24-minute isomer of ${\mathrm{Ag}}^{106}$ was produced by the ($\gamma , n$) reaction on metallic silver. A conversion line of a 512-kev gamma-ray was found. The activity has a positron group of energy 1.96 Mev, a weak lower energy positron, and a possible weak negative beta-group. An upper limit of 0.1 percent is placed on the positron component in the 8-day isomer of ${\mathrm{Ag}}^{106}$. Previously unreported conversion lines of 66-minute half-life were found in silver following bombardment of Pd by deuterons.
