Positron Annihilation in Undercooled Water and Ice

Abstract:

Article Preview

Positron lifetime and Doppler broadened annihilation line at wide temperature range 15-300 K was measured. The phase transition at melting temperature and its temperature shift in undercooled water was observed. The change in temperature dependence of long lifetime component in region 150 K was observed. The lifetime distributions (by program MELT) were calculated in full temperature range with an accent for the phase transition temperature range.
