Resonant antineutrino induced electron capture with low energy bound-beta beams
Antineutrino induced electron capture is a resonant process that can have a large cross-section for beams of monochromatic antineutrinos.

Summary: | Antineutrino induced electron capture is a resonant process that can have a large cross-section for beams of monochromatic antineutrinos. We calculate the cross-section of this process and investigate an experimental setup where monochromatic antineutrinos are produced from the bound-beta decay of fully ionized radioactive atoms in a storage ring. If the energy between the source and the target is well matched, the cross-sections can be significantly larger than the cross-sections of commonly used non-resonant processes. The rate that can be achieved at a small distance between the source and two targets of 10

kg is up to one interaction per 8.3⋅10

decaying atoms. For a source-target distance corresponding to the first atmospheric neutrino oscillation maximum, the largest rate is one interaction per 3.2⋅10

decaying atoms, provided that extremely stringent monochromaticity conditions (10

or better) are achieved in future ion beams. |
