Abstract

One of the features of the triplet state of positronium (ortho-Positronium)atoms is its relatively longer lifetime when compared to the singlet states ofpositronium (para-Positronium) atoms. The most probable decay of ortho-Positronium is into three annihilation photons. In order to test the discretesymmetry using the time-reversal symmetry odd-operator, it is importantto identify ortho-Positronium decay. Identification of the decay of ortho-Positronium atoms by measuring the positronium annihilation lifetime withthe Jagiellonian-Positron Emission Tomograph (J-PET) is presented in this article.
