We calculate the one-hole spectral function for the polarized t-J model using exact diagonalization for a finite size cluster. A well-defined quasiparticle peak appears at the bottom of the spectrum for intermediate values of J. The momentum of the quasiparticle corresponding to the bottom of the ba
