Abstract.For the electron capture of 7Be in the metallic environments Pd and In the 7Be half-life was observed to increase by 0.9±0.2 and 0.7±0.2%, respectively, while in the insulator Li2O it was unchanged within experimental error (all samples cooled to T = 12K). The observations are consistent with the predictions of the Debye plasma model applied to the quasi-free electrons in the metals. 

The 198Au βhalf-life in the metal Au⋆

Abstract.For the β--decay of 198Au in a Au metallic environment the half-life was observed to be longer by 0.4±0.7% at room temperature (T = 293K) and by 4.0±0.7% when the metal was cooled to T =

First hint on a change of the 210Po alpha-decay half-life in the metal Cu

Abstract.In the metal Cu cooled to T = 12K the α-decay half-life of 210Po nuclides, located inside the metal, was measured to be shorter by 6.3±1.4% compared to that at room temperature.

Enhancement of β + -Decay Rate of 22 Na in Metal Pd at Low Temperature

Temperature dependence of nuclear decays in metallic environments is a controversial issue. We measured the temperature dependence of the β+-decay half-life of22Na implanted into the metal host of

Alpha-decay half-life of 221Fr in different environments

Abstract.A possible dependence of the alpha decay process on the solid-state environment of the decaying nucleus has been investigated by measuring the alpha-decay half-life of 221Fr at room

The effect of metallic environment and low temperature on the 253Es α decay rate

In recent publications it has been pointed out that the α decay of transuranic elements in nuclear waste can be considerably speeded up by putting them into metals. The proposed mechanism is based on

Deuterium-deuterium nuclear cross-sections in insulator and metallic environments

Abstract.The three-dimensional Thomas-Fermi (TF) model is used to simulate the variation of the d + d → t + p cross-section at low impact energies, when the target deuterium nucleus is embedded in

Search for Decay Rate Variation of 7Be in Pt and A1

The decay rate variation of 7Be implanted into platinum and aluminum host materials has been measured via detecting the 478 keV γ-rays from the first excited state of 7Li populated in the electron
