Σ-Hypernuclear (π−,K+) production
The (π−,K+) reaction is proposed as an optimalσ-hypernuclear production process on nuclear tagets. Several ingredients of this process are discussed in connection with the choice of appropriate target nuclei. For demonstration, the excitation functions are calculated for the (π−,K+) reaction on the56Fe and28Si targets by assuming a shallowσ well depth, varying the spin-orbit strength and smearing (conversion) widths.
