On the possibility of sourcing a mono-energetic $\bar{\nu}_{e}$ long baseline beta beam from bound beta decay

TL;DR

This paper qualitatively analyzes the feasibility of using bound beta decay of fully stripped ions as a mono-energetic anti-neutrino source for long baseline neutrino experiments, concluding it is not practical due to technological and resolution challenges.

Contribution

It provides a qualitative assessment of bound beta decay as a potential mono-energetic anti-neutrino source, highlighting key technological limitations.

Findings

Bound beta decay cannot be practically used as a mono-energetic anti-neutrino source

Technological challenges hinder the implementation of such a source

Energy resolution requirements are too demanding for current detector technology

Abstract

In this paper, the possibility of using fully stripped ions that can decay through bound beta decay to complement electron capture long baseline neutrino oscillation experiments is qualitatively analysed. The disadvantages of such a source are discussed through consideration of the technological challenges faced and the energy resolution required from the detector. It is concluded that ions that bound beta decay cannot be used as a source of mono-energetic anti-neutrinos in a realistic long baseline CP-even neutrino beam.
