Electric fields probe the symmetry of the ‘heavy hydrogen’ nucleus

Nature, Published online: 25 June 2026; doi:10.1038/d41586-026-02036-zThe response of the nucleus of a deuterium atom to electric fields shows no evidence of asymmetry, which is consistent with conventional theories of particle physics.
