W. ; Lingenfelter, R. E. Abstract Calculations of the time-dependent flux in the 847-keV gamma-ray line from the decay of Co-56 that might be expected from the type II supernova 1987 A in the LMC are presented. It is found that, for a wide range of assumed Co-56 and supernova ejecta masses, this line should be detectable by planned gamma-ray observations with flux sensitivities of about 0.0001 photons/sq cm sec. If this line is detected, the measurement of its time-dependent flux together with its width will make it possible to determine not only the mass of Co-56 produced by explosive nucleosynthesis, but also the total mass and energy of the ejecta, and hence the mass of the supernova's progenitor.
