Summary
The detection of partial muon capture rates in16O forms a sensitive detector for the induced pseudoscalar coupling constant. We here investigate the effects of nucleon velocity terms in the weak Hamiltonian and of realistic nuclear wave-functions. Their inclusion is essential for a correct treatment of the problem. In addition to the previously suggested detector level, we find that capture into the ground state of16N permits an almost complete elimination of nuclear physics by comparison to the β-decay rate.
Riassunto
La rivelazione dei rapporti parziali di cattura muonica nel16O costituisce un sensibile rivelatore per la costante di accoppiamento pseudoscalare indotto. Qui si studiano gli effetti sull’hamiltoniana debole dei termini contenenti la velocità del nucleone e delle funzioni d’onde nucleari realistiche. La loro inclusione è essenziale per una corretta trattazione del problema. In aggiunta al livello di rivelazione suggerito precedentemente, si trova che la cattura nello stato fondamentale del16N permette una eliminazione quasi completa della fisica nucleare in confronto al rapporto di decadimento β.
