Sz. Vass et al., POSITRON-ANNIHILATION IN NONSIMPLE LIQUIDS - NORMAL-HEXANE, Journal of radioanalytical and nuclear chemistry, 190(2), 1995, pp. 457-462
Positron lifetime measurements were carried out in normal hexane vs. t
emperature in the range of 12.5 - 62.5 degrees C. The evaluation of th
e lifetime spectra indicates the presence of four lifetime components,
as published first by Jacobsen et al. An attempt is made to interpret
s the properties of the longest-living two components in terms of the
microscopic structure of the liquid.
