Description
Motivated by the lack of x-rays below ∼200 keV in most GRB spectra, we consider a spectral model in which an underlying source of power-law of gamma rays is shielded by an optically thick layer of absorbing circumburster material rich in iron-group elements whose photoelectric opacity exceeds Thomson opacity below ∼200 keV. For reasonable distributions of line-of-sight optical depths we find that the absorbed spectrum can indeed mimic the typical observed GRB spectra
