    We measured the invariant mass of the η ′ ( 958 ) meson through the η ′ → γ γ decay channel to search for possible character change of η ′ in a nuclear medium. The measured invariant-mass spectra were analyzed by fitting realistic spectral functions. An enhancement was observed in the lower tail of the η ′ mass peak for low-momentum ( P γ γ < 1     GeV / c ) events. Three statistical methods were applied to assess the significance of the enhancement. All methods yield a statistical significance above 3.7 σ . The spectral fitting indicates a mass reduction of 57.5 − 27.8 + 5.7     MeV / c 2 . Our result provides the first evidence for an in-medium spectral modification of the η ′ meson obtained through a direct measurement of its invariant mass.
