Conductivities in normal metals from measurements on superconductors

Abstract

A calculation of the high temperature electrical resistivity for lead, indium and tin is performed starting from data obtained when the gap equation for tunneling in superconductors is inverted. A main result is the average \ (\ overline {1 - \ cos \ Theta} \) whereΘ is the scattering angle. The result is discussed in detail.

Résumé

On a calculé la résistivité électrique à haute température du plomb, de l’indium et de l’étain en partant de l’équation du gap pour l’effet tunnel dans les supraconducteurs. Le résultat principal se révèle dans l’expression moyenne \ (\ overline {1 - \ cos \ Theta} \) oùΘ est l’angle de dispersion. Une discussion details de ce résultat dates ce travail.

Summary

We calculate the electrical conductivity at high temperatures in lead, indium and tin, based on experiments in the superconducting state (inversion of the “gap equation”). A main result is the mean value \ (\ overline {1 - \ cos \ Theta} \), whereΘ the scattering angle means. The result is discussed in detail.
