  We have calculated the high temperature series for the momentum distribution
function n_k of the 2D t-J model to 12th order in inverse temperature. By
extrapolating the series to T=0.2J we investigate the possibility of hole
pockets in the t-J model. We find no indication of hole pockets at an electron
density of n=0.9 with J/t=0.5 or J/t=1.0.
