Summary:163Ho has been considered as a suitable candidate for the capture of relic antineutrinos. However, the detection of the relic antineutrino using 163Ho is extremely challenging with current techniques. Therefore, we have searched for new targets for relic antineutrino detections through the resonant capture on nuclides undergoing electron capture. We have investigated nuclear and atomic properties of all nuclides. And we finally propose 131Ba, 159Dy, 175Hf, 195Au, and 243Cm as new candidates for the relic antineutrino detection, and call for high precise experiments of QEC-values and intensities of EC decays for these new candidates.
