Abstract
Published data on positron annihilation lifetime in copper as a function of grain size have been analyzed to show that there is a linear relationship between the internal grain boundary surface area, per unit volume, S v, and the positron lifetime, τ. The analysis indicates that grain boundaries are important in the trapping of positrons. It is suggested that the slope of the resulting straight line, dS v/dτ, can be used to determine the annihilation rate of the grain boundaries. © 1977 Springer-Verlag.
