Influence of Temperature on Intratrack Processes and Ps Formation and Behaviour in Liquid Water

摘要：

Positron annihilation lifetime (PAL) spectra are measured in liquid water in the temperature range 2 - 930C. The spectra are treated by taking into account intratrack reactions and assuming that radical reactions with Ps are diffusion-controlled (the respective temperature dependences obeying the Stokes-Einstein law). Equilibrium Ps bubble parameters are obtained.
