High-precision measurements of the shear modulus of polycrystalline indium from room temperature to the melting temperature T (m) and molecular statics computer simulation have been performed. It has been found that interstitial defects are intensely generated near T (m) in a dumbbell (split) configuration and their concentration can exceed the concentration of vacancies.
