概要

• 論文の詳細を見る

• Positron lifetime spectra have been measured in C../ C,. and graphite powders atroom temperature. It has been found that the spectrum for C../ C.. has only one component of lifetime 393 ps, whereas that for graphite has three components of lifetimes237 ps, 455 ps, and 88 ns. The single component in C../ C,. does not originate frompositronium. Considering its lifetime, the positron's ground state in C../C,. is sup-posed to be localized in the periodic free space of the C../C.. crystal structure.C.., graphite, positron annihilation, positronium
