Orthopositronium: Annihilation of positron in gaseous neon
arXiv:quant-ph/0303166
Abstract
On the basis of phenomenological model of the orthopositronium annihilation "isotope anomaly" in gaseous neon (lifetime spectra, positrons source Na-22) the realistic estimation of an additinal mode ~0.2%) of the orthopositronium annihilation is received.
