Abstract
Reported A-15 phases are tabulated using a comparison between measured and predicted lattice parameter as a criterion. An enlarged set of Geller radii is calculated, and trends in these are used to discuss electronic features of these compounds. The small variation of superconductingT c among some compounds related to Nb3Sn is explained in terms of constant electronic feature deduced from the Geller radii.
