Abstract
A recent theory of the resonant neutron scattering peaks in YBCO super conductors predicts the existence of a sharp spin-triplet two-particle collective mode (the ''pi resonance'') in the normal state. In this p aper, we propose an experiment in which the rr resonance could be prob ed directly in a two-particle tunneling measurement.
