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 evidence of quasi-free positronium state in GiPS-AMOC spectra of glycerol

D. Zvezhinskiy, M. Butterling, A. Wagner +2

We present the results of processing of Age-Momentum Correlation (AMOC) spectra that were measured for glycerol by the Gamma-induced positron spectroscopy (GiPS) facility. Our rese…

Beyond the Point Ps Approximation

Sergey V. Stepanov, Dmitry S. Zvezhinskiy, Vsevolod M. Byakov

In application to positron annihilation spectroscopy, Ps atom is considered not as a point particle, but as a finite size e+ e- pair localized in a bubble-state in a medium. Variat…

Effects of local heating and premelting in the terminal part of the e track

Dmitry S. Zvezhinskiy, Sergey V. Stepanov, Vsevolod M. Byakov +1

Due to the ionizations promoted by the slowing down of energetic positron and subsequent ion-electron recombinations, positron releases up to 1 keV in the terminal blob region [1].…

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…
