Summary
The transition probabilities for the competing reactions resulting from the absorption of slow negative kaons in hydrogen and deuterium have been calculated on the basis of a simple model. Computations were carried out for scalar and pseudoscalar coupling of the kaon from the Is and2p orbitals of the appropriate K-mesio atom. The absorption from the2p state is enhanced with respect to the pion case because of the smaller size of the orbit. This effect tends to reduce the possibility of distinguishing between the scalar and pseudoscalar character of the kaon coupling in strong interactions. The emission of a single pion is favoured for deuterium as well as for hydrogen. Qualitative conclusions are drawn concerning the relative importance of the other modes of kaon absorption in both hydrogen and deuterium.
Riassunto
Sulla base di un semplice modello si sono calculate le probabilità di transizione per le reazioni concorrenti risultanti dall’assorbimento in idrogeno di mesoni K negativi lenti. I calcoli sono stati fatti per gli accoppiamenti scalare e pseudoscalare del mesone K da parte degli orbitali Is e2p dei differenti atomi K- mesici. L’assorbimento da parte dello stato 2p è favorito rispetto al caso del pione data la minor dimensione dell’orbita. Quest’efietto tende a ridurre la possibilità di distinguere tra i caratteri scalare e pseudoscalare dell’accoppiamento dei mesoni K nelle interazioni forti. L’emissione di un singolo pione è favorita sia nel deuterio che nell’idrogeno. Si traggono conclusioni qualitative concernenti l’importanza relativa degli altri modi di assorbimento dei mesoni K sia in idrogeno che in deuterio.
