Electron mass conversion during electron capture

Click For Summary

Discussion Overview

The discussion centers on the process of electron capture, specifically examining whether the mass of the electron is converted into energy in the form of gamma radiation during this process. The scope includes theoretical considerations and interpretations of the mechanisms involved in electron capture and subsequent energy release.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the mass of the electron is converted into energy as gamma radiation during electron capture, without considering the mass differences involved.
  • Another participant counters this claim, asserting that the mass of the electron is not converted into gamma radiation, referencing an external source for support.
  • A different viewpoint indicates that while photon emission is possible, it is generally unlikely, with most energy going to the emitted neutrino and a small portion to the recoil of the nucleus.
  • Additionally, it is noted that after electron capture, an electron from an outer shell may drop into the inner shell, leading to energy release either through photon radiation or by ionizing the atom through the ejection of another outer shell electron.

Areas of Agreement / Disagreement

Participants express differing views on the conversion of electron mass into energy during electron capture, with no consensus reached regarding the specifics of energy release mechanisms.

Contextual Notes

The discussion involves assumptions about the roles of emitted particles and the conditions under which energy is released, which remain unresolved.

In electron capture, a proton turns into a neutron and a neutrino is emitted. Is (without counting the mass difference between neutron and proton and the mass of the neutrino) the mass of the electron converted into energy in the form of gamma radiation?

The emission of a photon is possible but unlikely. Usually all the energy goes to the neutrino (a tiny bit goes into recoil of the nucleus).

That said, what happens after electron capture is that there is an opening in one of the inner shells. As an electron from an outer shell drops into that orbit, there is an energy release either by radiating a photon or by ejecting another outer shell electron from the atom (thus ionising the atom).
