Findings

Shell structure enhances pairing interaction.

Predicted increase in critical temperature.

Potential for improved superconducting properties.

Abstract

The presence of shell structure and the accompanying high level degeneracy leads to a strengthening of the pairing interaction in some metallic nanoclusters and ions. It is predicted that for some specific systems one can expect a large increase in the values of the critical temperature and other parameters.
