Decay rate and spectrum of electrons from μ-mesons of theK-shell

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The decay rate of a μ meson from theK-shell of a light nucleus is evaluated as a function of the momentum of the produced electron and of the atomic number, taking into account the main electrostatic corrections on the usual, plane wave eigenfunctions of the electron, by a Born-like approximation. Such corrections change appreciably the decay rate and the shape of the spectrum (mainly, its lowest part) of the emitted electrons.

Riassunto

Si è calcolata la probabilità di decadimento di un mesone μ, legato nelK-shell d’un nucleo leggero, in funzione del momento dell’elettrone di decadimento. Le correzioni dovute all’interazione elettrostatica fra elettrone e nucleo modificano sensibilmente la probabilità di decadimento e, soprattutto, lo spettro degli elettroni emessi.
