Correlation between positron lifetime spectroscopy and self-diffusion parameters in indium

Weiler and Schaefer (1985) have recently published vacancy formation parameters for indium from a detailed analysis of positron lifetime spectra. Flower et al. (1985) have simultaneously published the pressure variation of the elastic constants. It is shown that these two sets of data when combined with earlier self-diffusion studies are interconnected through a thermodynamic relation published by Varotsos and Alexopoulos (1986).
