Description

By taking the 88Y core excitation into account, detailed structure calculation of Λ89Y has been performed. The wave functions are used to analyse the observed 89Y(π+, K+)Λ89Y spectrum within the framework of DWIA. It is clarified for the first time that the double-like substructure in each major peak should not be attributed to the Λ spin-orbit splitting but is due to the effect of nuclear core excitation. The small spin-orbit splitting obtained in this analysis is consistent with the two data in light hypernuclei ( Λ9Be and Λ13C). (author)
