Resum
The whole set of INTEGRAL observations of Type Ia supernova SN 2014J, covering the period 19–162 days after the explosion, has been analyzed. For spectral fitting the data are split into early and late periods covering days 19–35 and 50–162, respectively, optimized for 56Ni and 56Co lines. As expected for the early period, much of the gamma-ray signal is confined to energies below ~200 keV, while for the late period it is strongest above 400 keV. 56In particular, in the late period, Co lin...
