To explain the experimental spectra for angle-resolved photoemission w
e consider a modified t-J model. The modified model includes next-near
est(t') and next-next-nearest (t '') hopping as well as corrections du
e to ''virtual'' charge fluctuations to the spectral weights. A Dyson
equation that relates the single-hole Green's functions for a given ps
eudospin and given spin is derived and is compared to experimental res
ults. [S0163-1829(97)04438-X].
