Abstract / Description:The low energy spectra of some gamma-ray
bursts show excess components beside the
power-law dependence. The consequences of such a
feature allows us to estimate the gamma
photometric redshift of long gamma-ray bursts in
the BATSE Catalog. There is a good correlation
between the measured optical and the estimated
gamma photometric redshifts. The estimated
redshift values for long bright gamma-ray bursts
are up to z=4, while for long faint bursts the
redshifts cannot be determined unambiguously by
this method (they should be up to z=20). The
redshift distribution of all the gamma-ray bursts
with known optical redshifts agrees quite well
with the BATSE-based gamma photometric redshift
