Query: New targets for relic antineutrino capture   The electron capture (EC) decaying $^{163}$Ho has been a candidate for
measuring the electron neutrino mass since a long time and recently the
interest in $^{163}$Ho has been renewed also because of a possible relic
antineutrino capture experiment. However, if there is no overdensity in the
antineutrino distribution, the detection of relic antineutrinos using
$^{163}$Ho is extremely challenging with current techniques. We have searched
for new possible candidates to detect relic antineutrinos by resonant
absorption in EC decaying nuclei. We propose $^{131}$Ba, $^{159}$Dy,
$^{175}$Hf, $^{195}$Au, and $^{243}$Cm as new possible targets for the relic
antineutrino capture and call for highly precise experiments of the $Q_{EC}$
values for these new candidates.
