The (Kstopped-, π0) strangeness and charge changing reaction was investigated by producing a λ12B 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) ×10-3 and (0.35±0.09) ×10-3, respectively, which after correction for isospin was lower than a previously measured value for the 12C(Kstopped-, π-) λ12C 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 Kstopped- reaction limits its usefulness in the study of new hypernuclear species.
