A. Zecca et al., COUNTING-RATE-DEPENDENCE OF THE S-PARAMETER IN DOPPLER-BROADENING POSITRON-ANNIHILATION MEASUREMENTS, Measurement science & technology, 5(1), 1994, pp. 61-64
The dependence of the S parameter in Doppler-broadening positron beam
experiments on the counting rate has been studied. The advantages of d
ifferent correction or compensation techniques are assessed.
