摘　　要：Ⅰ. INTRODUCTION Mass spectra for complexes of β-diketones of rare earth elements have already been studied. But most of them are those in which the rare earth elements coordinate to diketones with fluorated alkanes or heterocyclic rings. The mass spectra for complexes of 1-phenyl-3-methyl-4-(-benzoylacetyl)-pyrazolone-5 with La, Eu or Tb, the synthesis of this ligand and the study on the mass spectra of its RE-complexes are reported for the first time.
