Summary:For the last few decades the (π+, K+) reaction has played an important role in heavy hypernuclear spectroscopy where the Λ spin-orbit splitting should be one of the most interesting subjects. In this article, first, various stages of calculational frameworks for hypernuclear production cross sections are discussed. Then, focusing on the 89Y(π+, K+)89ΛY experimental data, new DWIA analysis has been carried out by taking full account of the core nuclear excitation effects. As a result we found that one of the doublet peaks comes from the nuclear core excitation and that the Λ spin-orbit splitting is small in consistent with the finding in the p-shell hypernuclei.
