| 英文摘要 | Lusignoli and Vignati have recently pointed out that it is in principle possible to directly detect the cosmic antineutrino background (C (v) over barB) by using the rather stable isotope (163)Ho as a target, which can decay into (163)Dy via electron capture (EC) with a very small energy release. In this Letter we calculate the rate of the relic antineutrino capture on (163)Ho nuclei against the corresponding EC decay rate by taking account of different neutrino mass hierarchies and reasonable values of theta(13). We show that such flavor effects are appreciable and even important in some cases, and stress that a calorimetric measurement of the C (v) over barB might be feasible in the far future.
