Abstract
Positron annihilation lifetime (LS) and Doppler broadening annihilation radiation lineshape (DBARL) were measured at room temperature in a series of solid acetylacetonate chelates involving metals of different groups. The LS and DBARL obtained parameters were associated with the electronic configuration of the central metal ions and their electronic spectra.
