The studied systems can be classified in two groups: the first one presenting only inhibition of positronium formation and the second one presenting inhibition and quenching effects. The inhibition and quenching constants were determined.en-USrestritoArtigo publicado em periodicohttps://jp4.journaldephysique.org/articles/jp4/abs/1993/04/jp4199303C428/jp4199303C428.htmlhttps://doi.org/10.1051/jp4:1993428
