Positronium in a Liquid Phase: Formation, Bubble State and Chemical Reactions

Figure 8

Temperature dependence of the lifetime, 𝜏₃, of the long-lived component in pure water. Experimental data are derived from a 3-exponential deconvolution of the spectra [13–17] and theoretical predictions are based on the standard models of the Ps bubble (finite potential well: solid line; infinite potential well: dashed line) [18].
