Lusignoli and Vignati have recently pointed out that it is in principle possible to directly detect the cosmic antineutrino background (Cν¯B) by using the rather stable isotope163Ho as a target, which can decay into163Dy via electron capture (EC) with a very small energy release. In this Letter we calculate the rate of the relic antineutrino capture on163Ho nuclei against the corresponding EC decay rate by taking account of different neutrino mass hierarchies and reasonable values of θ13. We show that such flavor effects are appreciable and even important in some cases, and stress that a calorimetric measurement of the Cν¯B might be feasible in the far future.
