Abstract

The Solar Maximum Mission satellite did not record any γ-ray counts in excess of the background for a time interval of 223 s after the arrival of the first ν_e's from the supernova 1987A. On the basis of the original data we derive a new 3σ upper limit on the γ fluence for this period and derive improved bounds on the ν_i → ν_jγ and ν_T → ν_ee^-e⁺γ radiative decay channels for neutrino masses up to the experimentally allowed value of around 30 MeV.
