The density of quenched gold

Abstract

A precision hydrostatic differential method for measuring small density differences of solid bodies was used to determine the activation energy of vacancy formation and migration in quenched gold. The values were found to beE f =0·76 eV, andE m =0·51 eV.E f is substantially lower than the well established value 0·96 eV, whereasE m is close to the value 0·56 eV determined by Jeannette and Machlin for oxygen-free gold.

The concentration of vacancies determined from our measurement is of the same order as the absolute calorimetric determination by DeSorbo.
