Description

The results of two years observations of SN1987A hard X radiation by the Hexe instrument onboard the Kvant module are summarized. By May-June, 1989 the hard X radiation flux has declined more than 8 times in comparison with the maximum of X radiation light curve. The upper limit on the ratio of 57Co/56Co abundances at the level of three standard deviations is obtained. It exceeds the ratio of 57Fe/56Fe abundances at the Earth in 1.5 times
