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



First hints on a change of the 22Na βdecay half-life in the metal Pd

Abstract.For the β+-decay of 22Na in the metallic environment Pd cooled to T = 12 K the 22Na half-life was observed to be shorter by 1.2±0.2%. The result is consistent with --but lower than-- the

Enhanced electron screening in d(d,p)t for deuterated metals

Abstract.The electron screening effect in the d(d,p)t reaction has been studied for deuterated metals, insulators, and semiconductors, i.e. 58 samples in total. As compared to measurements performed

Oppenheimer-Phillips effect and electron screening ind+ d fusion reactions

Thed(d, n)3He andd(d,p)t fusion reactions have been studied at center-of-mass energies E=1.6 to 130 keV using intense beam currents from 30, 100, and 450 kV accelerators in combination with detectors

Low-energy S(E) factor of 9Be(p, α)6Li and 9Be(p, d)8Be

Excitation functions and angular distributions of the 9Be(p, α)6Li and 9Be(p, d)8Be reactions have been measured over the energy range Ep = 16 to 390 keV. The data are dominated by one broad

High-Z electron screening: the cases 50V(p,n)50Cr and 176Lu(p,n)176Hf

The electron screening in 50V(p,n)50Cr has been studied at Ep = 0.75 to 1.55 MeV for different environments: VO2 insulator, V metal and PdV10% alloy. Relative to the insulator we find for the metal
