✦ Synopsis

In this paper we present a study of the interaction of low energy electron antineutrino on nuclei that undergo electronic capture. We show that the two crossed reactions that could be obtained have a sizable cross section and are both suitable to detect low energy antineutrino. The presence of an energy threshold in one case and the absence of a suitable final state in the other prevent the detection of Cosmological Relic antineutrino background unless very specific conditions on the -value of the decay are met or significant improvements on the performances of ion storage rings are achieved.
