Abstract

The annihilation frequencies of 19 p̄p annihilation reactions at rest obtained in different target densities are analysed in order to determine the values of the P -wave annihilation percentage at each target density and the average hadronic branching ratios from P - and S-states. Both the assumptions of linear dependence of the annihilation frequencies on the P - wave annihilation percentage of the protonium state and the approach with the enhancement factors of Batty are considered. Furthermore the cases of incompatible measurements are discussed.
