Reassessment of the conduction-electron spin resonance of alkali metals in zeolites

Abstract
Blatter, Blazey, and Portis [Phys. Rev. B 44, 2800 (1991)] interpreted observed electron-spin-resonance spectra in terms of small Na-Cs alloy clusters residing within the pores of zeolite Y. It is the purpose of this paper to reinterpret these important results in the light of recent developments.
