Summary
An investigation is made of the atomic capture of K−-mesons by the atoms of nuclear emulsion. The initial population of the mesic capture states is estimated; from this population distribution a detailed cascade calculation is performed. The energy spectrum of the Auger electrons ejected during the de-excitation of the mesic atom is given and the intensities of certain X-ray lines are shown to be dependent on the properties of the nuclear surface. The probabilities of nuclear capture of the meson from the various mesic states are found, and the probability that a A0-hyperon, produced as a result of this nuclear capture, is trapped within the nucleus is determined. Similar calculations that have been made for ∑−-hyperic atoms are also included.
Riassunto
Si studia la cattura atomica di mesoni K− negli atomi dell ’emulsione nucleare. Si valuta la popolazione iniziale degli stati di cattura mesici; in base a questa distribuzione della popolazione si effettua un dettagliato calcolo della cascata. Si dà lo spettro di energia degli elettroni di Auger emessi durante la diseccitazione dell ’atomo mesico e si dimostra che le intensità di alcune linee dello spettro dei raggi X dipendono dalle proprietà della superficie nucleare. Si trovano le probabilità di cattura del mesone nei vari stati mesici e si determina la probabilità che un iperone Ao, prodottosi in conseguenza di questa cattura nucleare, sia catturato entro il nucleo. Si includono anche calcoli analoghi eseguiti per atomi ∑−-iperonici.
