Summary
A discussion of the main parameters of muonic-hydrogen formation in low-pressure targets (10−2 Torr <P<10 Torr) is presented. Particularly we discuss, as a function of the pressure, the function of captured muons, the velocity distribution of the μp atoms and the time evolution of the 2S population.
Riassunto
Questo lavoro si articola sulla discussione dei parametri principali che regolano la formazione di idrogeno muonico a basse pressioni (10−2 Torr <P<10 Torr). In particolare, si trattano la frazione di muoni catturati, in funzione della pressione, la distribuzione in velocità e l’evoluzione temporale della popolazione dello stato 2S degli atomi μp formati.
Реэюме
Обсуждаются основные параметры обраэования мю-водорода в мищенях при ниэких давлениях (10−2 Top <P<10 Top). В частности, мы исследуем долю эахваченных мюонов, распределение скоростей μp атомов и временную зволюцию 2S эаселенности в эависимости от давления.

We are assuming room temperature as a working condition; for this case, a pressureP=1 Torr corresponds to a density ϱ=7.1·1016 hydrogen atoms/cm3.
