2 (2014) 21 27 Japanese Positron Science Society . . Positron lifetime measurement technique . Abstract: The basic principles of the positron lifetime measurement technique are described. The topics are as follows: (1) timing measurements of creation and annihilation of positrons, (2) -ray detector, (3) signal processing for the -ray timing, (4) positron lifetime spectrum, (5) data analysis, and (6) fundamental annihi- lation process. Keywords: positron, positron lifetime, measurement method, ray, -ray detector, scintillation detector, life- time spectrum 1. . . . . . . . 106 107 . . . 2. . 1 . 2 . 511 keV 3 0 511 keV . 11 12 . . + . . . . . 22.
