摘要: Abstract Analyzing positron annihilation data it was found that the formation energy of a single vacancy is proportional to characteristic temperature Tc in f.c.c. metals. Assuming equilibrium fractional concentrations vacancies at are constant, one finds entropy (1.6 ± 0.1)k for all For zinc and cadmium, entropies 2.5k 3.3k respectively.
