  $^{163}$Ho has been considered as a suitable candidate for the capture of
relic antineutrinos. However, the detection of the relic antineutrino using
$^{163}$Ho 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 $^{131}$Ba,
$^{159}$Dy, $^{175}$Hf, $^{195}$Au, and $^{243}$Cm as new candidates for the
relic antineutrino detection, and call for high precise experiments of $Q_{\rm
EC}$-values and intensities of EC decays for these new candidates.
