The first 
-ray spectroscopy of -shell hypernucleus, F, is performed in June, 2015 at the J-PARC K1.8 beam line (J-PARC E13). Precise energy levels of F can be revealed by measured rays in this experiment. Especially, the strength of 
spin-spin interaction in -shell hypernucleus is obtained through the energy spacing of the ground-state doublet of the hypernucleus. By comparing its strength between the 
, 
, and -shell hypernuclei, a radial dependence interaction is investigated. The hypernucleus is produced through the 
reaction with the beam momentum of 1.8 GeV/c. In very preliminary results, we observed two rays, and their energies are 
keV and 
keV where the uncertainties are only statistical.
