✦ Synopsis

Differexes were observed in the lifetime spectra of positron annihilation in L and D isomers of some amino acids. The intensity of the triplet component was found to be grcarer in D isomers than in L isomers TWO possible explanations are discussed

## Abstract The annihilation rates of thermalized positrons in the semimetals bismuth and antimony were measured. We found that the different rates were not based on the various conduction‐electron densities. However, excellent agreement with experimental results was achieved by taking into conside

Structural relaxation processes are reported in polystyrene as a function of ageing time using positron annihilation lifetime and Doppler broadening spectroscopy. Changes in the intensity, lifetimes and line shapes with increasing temperature for ortho positronium annihilation show an internal consi
