| contents | We discuss new spin observables presently accessible to measurement in the proton-deuteron (pd) system, namely polarization transfer coefficients from doubly spin-polarized initial state to the outgoing nucleon in the elastic nucleon-deuteron (Nd) scattering and in the nucleon-induced deuteron breakup reactions. The sensitivity of these observables to three-nucleon force (3NF) effects is investigated and compared to sensitivities of the constituent standard single polarization transfer coefficients in the neutron-deuteron (nd) system. $K_{y,y}^{y'}$ in elastic nd scattering, for which large 3NF effects, up to 40\%, have been found at higher energies, seems the most promising observable to measure. |
