We discuss, in the context of precision measurement of Δ m 2 31 and θ 13 , physics capabilities enabled by the recoilless resonant absorption of a monochromatic antineutrino beam enhanced by the Mössbauer effect recently proposed by Raghavan. Under the assumption of a small relative systematic error of the level of a few tenths of a per cent between measurements at different detector locations, we give analytical and numerical estimates of the sensitivities to Δ m 2 31 and sin 2 2θ 13 . The accuracies of their determination are enormous; the fractional uncertainty in Δ m 2 31 achievable by ten point measurement is 0.6% (2.4%) for sin 2 2θ 13 = 0.05, and the uncertainty of sin 2 2θ 13 is 0.002 (0.008) both at 1σ confidence level (CL) with the optimistic (pessimistic) assumption of systematic error of 0.2% (1%). The former opens a new possibility of determining the neutrino mass hierarchy by comparing the measured value of Δ m 2 31 with that from accelerator experiments, while the latter will help to resolve the θ 23 octant degeneracy.
