The positron lifetimes in alkali halides are calculated assuming the outer shell electrons of the halide ion to form an 'electron plasma' which is capable of concentrating around the positron. The calculated annihilation rates are found to be in good agreement with the experimental results.

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
