LIFETIME OF POSITRONS IN LIQUIDS AT HIGH PRESSURE

Abstract

The examination of the microscopic nature of a liquid by the use of positronium lifetime is unique in that the positronium lifetime depends on the size of regions of low density whereas x-ray and neutron diffraction depend on where the molecules are most dense. The reversal of the sign of the temperature effect on the lifetime is the most unusual effect observed here. Further work on x-ray diffraction at high pressure on liquids would help in the interpretation of the present results. (Author)
