Description
Temperature dependence of nuclear decays in metallic environments is a controversial issue. We measured the temperature dependence of the β+-decay half-life of 22Na implanted into the metal host of palladium. It is found that the β+-decay half-life of 22Na in the metal Pd cooled to T=15K is shorter by 0.46(14)% than that at room temperature. The result is consistent in sign with, but clearly smaller than, the estimated one by the Debye model. (authors)
