From a group of double stars which were produced by 4.5 Bev negative pions, a selection has been made of those events with linking tracks longer than 20 mu m and which appeared to represent the non-mesonic decays, mainly, of / Be hyperfragments. A total of 31 hyperfragments satisfied these criteria. From a study of the energy distribution of the charged particles from these disintegrations, it has been found possible to separate the decays into those where the hyperon was stimulated into decaying by a neutron, from those caused by a proton. The ratio of neutron to proton stimulation is found to be about 1.4. This value may give some indications about the parity of the DELTA hyperon and the possible transition DELTA yields SIGMA + pi .
