✦ Synopsis

Positron annihilation lifetimes and Doppler-broadened annihilation lines have been measured in solid Ln(aa),, where Ln = La, Sm, Eu, Gd, Dy, Ho, Er, Tm and aa=CH,COCHCOCHx. The results point to the formation of positronium in all complexes except that of europium. This result is attributed to a charge-transfer process ligand+metal in the europium compound and metal-tligand in the others,

A computational technique is developed to evaluate positron distribution as well as the electron-positron momentum densities in diamond and the use of these provide us the means of interpreting the k-space densities obtained experimentally using the two-dimensional angular correlation of annihilatio
