Formation of quasi-free and bubble positronium states in water and aqueous solutions
Serge V. Stepanov, Gilles Duplâtre, Vsevolod M. Byakov +2
It is shown that in aqueous solutions a positronium atom is first formed in the quasi-free state, and, after 50-100 ps, becomes localized in a nanobubble. Analysis of the annihilat…
The Determination of Microscopic Surface Tension of Liquids with a Curved Interphase Boundary by Means of Positron Spectroscopy
Sergey V. Stepanov, Vsevolod M. Byakov, Olga P. Stepanova
The method for determination the microscopic surface tension of nanobubbles is developed based on the new elaboration of the positronium bubble model. In contrast to existin…
Electric field effect on positronium formation in liquids
Sergey V. Stepanov, Vsevolod M. Byakov
The comparison of different models (the Ore, spur and blob models) of positronium (Ps) formation is presented. Because in molecular media Ps is formed in the terminal positron blob…
