The BNL-AGS/E929 experiment was carried out to study energy levels of the Λ13C hypernucleus by a gamma-ray spectroscopy. Energy splitting of the spin-orbit doublets, 1/2- and 3/2- states, was estimated precisely. The excitation energy of the 1st 3/2+ state was also measured. We discuss the symmetric and the anti-symmetric spin-orbit interactions between a Λ particle and a nucleon from the measurement.
