Astrophysics and Cosmic Phenomena

Distributions of the Bjorken scaling variables $x$ and $y$, and the structure function ${F}_{+}(x)$, are presented both for neutral-current and for charged-current ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ interactions. The data were obtained by use of the Fermilab 15-ft neon bubble chamber exposed to a narrow-band ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ beam. Results are based on 151 neutral-current and 683 charged-current events. An important feature of the neutral-current analysis is the event-by-event reconstruction of the outgoing neutrino.
