Measurement of double-polarization asymmetries in the quasi-elastic $^3\vec{\mathrm{He}}(\vec{\mathrm{e}},\mathrm{e}'\mathrm{p})$ process
Abstract
We report on a precise measurement of double-polarization asymmetries in electron-induced breakup of proceeding to and final states, performed in quasi-elastic kinematics at for missing momenta up to . These observables represent highly sensitive tools to investigate the electromagnetic and spin structure of 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 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.
