Using a germanium detector array, Hyperball, we have measured γ rays from several Λ hypernuclei. In the previous experiments, spin-dependence of ΛN effective interaction was investigated. In the latest experiment, we have studied λ11B in which six γ transition have been observed. The result of this experiment suggests that the level structure is quite different from a theoretical prediction based on the ΛN spin-dependent effective interaction parameters determined in the previous experiments.
