| The standard form: of the positron annihilation lifetime spectroscopy results presentation are two plots of o-Ps lifetime and intensity as a function of external factor, e.g. temperature, pressure. Both o-Ps parameters change (stepwise) when in the medium phase transitions occur. For a more complete picture of the structural changes occurring in the matter we suggest to use an additional plot, in the coordinates, (τ3, I3). The hydrocarbons are selected to show the advantages following from the presentation of the results in the intensity-lifetime (INTI) plot. |
