Abstract
With a germanium detector array (Hyperball), we observed two [Formula presented]-ray peaks corresponding to the two transitions ([Formula presented] and [Formula presented]) in the [Formula presented] hypernucleus which was produced by the [Formula presented] reaction. The energies of the [Formula presented] rays are [Formula presented] and [Formula presented]. The energy difference was measured to be [Formula presented], which indicates a very small [Formula presented]-spin-dependent spin-orbit force between a [Formula presented] and a nucleon. This is the smallest level splitting by far ever measured in a hypernucleus.
