Scientific paper

Using a Monte Carlo code, gamma-ray lines produced by 56Co, 57Co and 44Ti are studied in terms of photon transport inside the envelope of the SN 1987A. Computations are compared with gamma-ray observations conducted by 8 different groups during three years. The results, mainly the line shifts and the line widths of 56Co lines put constraints on the models, in terms of mixing and fragmentation. An estimation of the predicted fluxes of 57Co and 44Ti lines and its effects on the bolometric light curve is presented.
