We theoretically study production of a ΛΛ hypernucleus CΛΛ16 in a (K−,K+) reaction on an 16O target at pK−=1.8 GeV/c, within a distorted-wave impulse approximation. The calculated spectrum provides promising peaks of the ΛΛ bound and excited states of CΛΛ16 in a one-step mechanism K−p→K+Ξ− via Ξ− do...
