Abstract: The (K-stopped, pi0) strangeness and charge changing reaction was investigated by producing a 12Blambda hypernucleus from a carbon target. The branching ratio for K- capture to the ground and p-shell states of this hypernucleus was found to be (0.28 +- 0.08)x10-3 and (0.35 +- 0.09)x10-3, respectively, which after correction for isospin was lower than a previously measured value for the 12C(K-stopped, pi-)12Clambda reaction, but still above the theoretical predictions for the ground state. The experiment obtained a missing-mass resolution comparable to in-flight reactions, however the higher background and lower selectivity of the K-stopped reaction limits its usefulness in experimental study of the 12C(K-stopped, pi0)12Blambda reaction.
