Anomalous helium-bubble growth in palladium

Physical Review B, 1994
Helium-bubble growth in \ensuremath{\alpha}-implanted palladium has been investigated by positron-lifetime measurements as a function of isothermal annealing time, t. The bubble radius shows first an expected ${\mathit{t}}^{1/6}$ variation and then an anomalous time dependence faster than ${\mathit{t}}^{1}$.

Structure of multielectron bubbles in liquid helium

Physical Review B, 1992
We present a detailed density-functional calculation for multielectron bubbles with charges {ital z}{le}50. The calculation is similar to that for metal clusters, but we found no obvious shell structure in the charged bubbles. The exchange-correlation interaction has the important effect of reducing the bubble radius and, hence, enhances its stability.

Superconductivity in Multielectron Bubbles in Helium

AIP Conference Proceedings, 2006
Superconductivity on a spherical, two‐dimensional surface is investigated in the context of multielectron bubbles in liquid helium, where the electron‐ripplon coupling is the underlying mechanism leading to pairing. In this contribution, we apply a BCS‐like self‐consistent mean‐field theory to calculate the superconducting gap.

Synergistic effects in hydrogen–helium bubbles

Journal of Physics: Condensed Matter, 2012
The detrimental effects of hydrogen and helium on structural materials undergoing irradiation are well documented, if not well understood. There is experimental evidence to suggest that a synergistic effect between the two elements exists, which results in increased damage when both are present.
