Scientific paper

The gamma-ray spectra of two delayed detonation models are obtained with a Monte Carlo gamma-ray deposition scheme which is related to a supernova light-curve model. The gamma-ray flux at 847 keV for the Co-56 line is forecast by the model for 'fast' type-Ia supernovae which suggests that gamma-ray observations can aid in identifying the SN Ia models. The gamma-ray flux at 847 keV predicted by the delayed detonation model for SN1991T leads to key changes to the original spectra when considered with the COMPTEL energy-response function.
