Positroniumformation in the adducts, except for the europium complex, was observed. These results are discussed in terms of the electronic properties of the central metal ions.en-USPositronium formation in lanthanide (III) trifluoroacetate with 3-picoline-N-oxide compounds.Artigo publicado em periodicoO periódico Chemical Physics Letters concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
