## Abstract

The [Formula Presented] hypernucleus was studied by measuring [Formula Presented] rays in coincidence with the [Formula Presented] reaction. [Formula Presented] rays from the [Formula Presented] and [Formula Presented] states, which are the partners of the spin-orbit doublet states with a predominant configuration of [Formula Presented] to the ground state were measured. The splitting of the states was found to be [Formula Presented] This value is 20–30 times smaller than that of single particle states in nuclei around this mass region. The [Formula Presented] state appeared higher in energy, as in normal nuclei. The value gives new insight into the [Formula Presented] interaction. The excitation energies of the [Formula Presented] and [Formula Presented] states were obtained as [Formula Presented] and [Formula Presented] respectively. We also observed [Formula Presented] rays from the [Formula Presented] state, which has a [Formula Presented] configuration, to the ground state in [Formula Presented] The excitation energy of the [Formula Presented] state was obtained as [Formula Presented] Nuclear [Formula Presented] rays with energies of 4.438 and 15.100 MeV had similar yields, which suggests that a quasifree knockout of a [Formula Presented] particle is dominant in highly excited regions.
