Direct experimental constraints on the spatial extent of a neutrino wavepacket
Nature, Published online: 12 February 2025; doi:10.1038/s41586-024-08479-6An innovative method using superconducting sensors precisely measures the recoil energy of lithium-7 nuclei, setting a lower limit on the spatial extent of neutrino wavepackets, advancing understanding of neutrino properties and weak nuclear decays.
