摘要：
The diffusion of 86Rb in potassium has been measured at six temperatures between 0°c and the melting point of potassium. The diffusion coefficients are given by the equation: D=0·090±0·028 exp (—8·78±0·18/RT) cm2 sec−1 where the activation energy is in kcal. mol.−1. The results are briefly discussed in terms of current theories of impurity diffusion by vacancies. © 1969 Taylor & Francis Group, LLC.
