We report on a precise measurement of double-polarization asymmetries in electron-induced breakup of He 3 proceeding to pd and ppn final states, performed in quasi-elastic kinematics at Q 2= 0.25 (GeV/c) 2 for missing momenta up to 250 MeV/c. These observables represent highly sensitive tools to investigate the electromagnetic and spin structure of He 3 and the relative importance of two-and three-body effects involved in the breakup reaction dynamics. The measured asymmetries cannot be satisfactorily reproduced by state-of-the-art calculations of He 3 unless their three-body segment is adjusted, indicating that the spin-dependent part of the nuclear interaction governing the three-body breakup process is much smaller than previously thought.
