Summary
The yield of O-Ps has been studied in moderately dense CO2 with a static electric field applied across the gas. The results are shown to be consistent with recent models of Ps formation which have considered that Ps is formed in molecular gases by both Ore and spur processes.
Riassunto
La produzione di O-Ps è stata studiata in CO2 moderatamente denso con un campo elettrico statico applicato attorono al gas. Si mostra che i risultati sono consistenti con recenti modelli di formazione di Ps che considerano che Ps sia formato in gas molecolari per mezzo dei processi di Ore e spur.
Реэюме
Исследуется выход O-Ps в умеренно плотном CO2 в случае статического электрического поля, приложенного к гаэу. Покаэывается, что реэулътаты согласуются с недавними моделями обраэования Ps которые предполагают, что Ps обраэуется в молекулярных гаэах.
