Abstract
We calculated the high temperature series for the momentum distribution fun ction ni of the two-dimensional t-J model to twelfth order in inverse tempe rature. By extrapolating the series to T = 0.2J we investigate the possibil ity of hole pocket, 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. (C) 1998 El sevier Science Ltd. All rights reserved.
