We have used complementary sets of normal and superconducting probes to study the nonequilibrium region near phase-slip centers in narrow superconducting strips. An exponentially decaying branch imbalance potential, μQ, is observed and the decay length, the quasiparticle diffusion length, is measured directly and compared to the phase-slip resistance.
