Abstract

The reaction

{}^{12}C

(

ν_{μ}

μ^{-}

)X has been measured near threshold using a

decay-in-flight

ν_{μ}

beam from the Los Alamos Meson Physics Facility and a massive liquid scintillator neutrino detector (LSND). In the energy region 123.7<

E_{ν}

<280 MeV, the measured spectral shape is consistent with that expected from the Fermi-gas model (FGM). However, the measured flux-averaged inclusive cross section {[8.3±0.7(stat)±1.6(syst)]×

10^{- 40}

{cm}^{2}

} is more than a factor of 2 lower than that predicted by the Fermi-gas model and by a recent random phase approximation calculation.
