Positron annihilation study of molecular liquid and the observation of its dynamics

摘要：

The behaviour of ortho-positronium in several molecular systems at different temperatures from 14K up to 310K will be reported. Observed differences of the o-Ps lifetime and the S-parameter for propylene glycol and propylene carbonate will be discussed from the point of view of a motion of molecules as well as a slow-downing of incoming relativistic positron.
