Abstract

We have studied the neutral-current reactions $ν_{μ} N \to ν_{μ} N^{'} π^{0}$ and ${\bar{ν}}_{μ} N \to {\bar{ν}}_{μ} N^{'} π^{0}$ and compared them to the charged-current reactions $ν_{μ} N \to μ^{-} N^{''} π^{0}$ and ${\bar{ν}}_{μ} N \to μ^{+} N^{''} π^{0}$ . We have measured the ratios ${R_{0}}^{'} = \frac{σ (ν_{μ} N \to ν_{μ} N^{'} π^{0})}{2 σ (ν_{μ} N \to μ^{-} N^{''} π^{0})}$ and ${\bar{R}}_{0}^{'} = \frac{σ ({\bar{ν}}_{μ} N \to {\bar{ν}}_{μ} N^{'} π^{0})}{2 σ ({\bar{ν}}_{μ} N \to μ^{+} N^{''} π^{0})}$ to be 0.17±0.04 and 0.39±0.18, respectively. We also present the $π^{0} p$ invariant-mass distribution of the neutrino-induced reactions.
