Ortho-para conversion of positronium in some rare-earth ion aqueous solutions

  • 1. Istituto di Fisica del Politecnico, Milan (Italy)

Description

We have extended a previous investigation by studying the ortho-para conversion of positronium in aqueous solutions of some lanthanide ions (Yb3+, Tm3+, Er3+, Dy3+, and Tb3+). The corresponding cross sections were found to be proportional to the number of unpaired electrons in the ion. Furthermore, the contact density of the electron-positron pair in the origin was obtained for a 1 M aqueous solution of Er Cl2. (Author) 21 refs., 2 figs., 2 tabs
