N2 - We calculate the cross section of the γ-ray production from neutral-current neutrino-oxygen quasi-elasticinteraction, ν+ 16O→ν+p+ 15N*, or ν+ 16O→ν+n+ 15O*, in which the residual nuclei ( 15N* or 15O*) lead to the γ-ray emission with E γ>6MeV at thebranching ratio of 41%. Above 200 MeV, this cross section dominates over that of γ-ray production from the inelastic reaction, ν+ 16O→+ 16O*. In the present calculation, spectral function and the spectroscopic factors of 1p 1/2, 1p 3/2 and 1s 1/2 states areessential. The γ-ray production is dominated by the deexcitation of 1p 3/2 state of the residual nucleus.
