Abstract

The first measurement of proton, pion, and kaon associated fission of Bi nuclei has been performed in a photon energy range 1.45 < E_γ < 1.55 GeV. The fission probabilities are compared with an inclusive fission probabilities obtained with photons, protons and pions. The fission probability of Bi nuclei in coincidence with kaons is 0.18 ± 0.06 which is ~3 times larger than the proton and pion associated fission probabilities and ~2 times larger than inclusive ones. The kaon associated excess fission events are explained in terms of bound Λ residual states and their weak nonmesonic decays.
