Abstract
A search for the possible decay of the antiproton has been carried out in a hydrogen bubble chamber exposed to a 0.76 GeV/c antiproton beam. As a result 161 odd-prong events with a net charge of -1 in the final state were observed. After subtracting the two types of background discussed in the paper we are left with a signal of 5 ± 16 events. From this a lower limit of 1.2 X 10-4s has been obtained for the antiproton lifetime with 95% confidence level.
