Abstract

The nucleon structure function,

F_{2}

, has been measured up to

q^{2} = 120

{(G e V / c)}^{2}

and for

40 < W^{2} < 300

Ge

V^{2}

. The data exhibit a significant pattern of scaling violation. Compared to lower-energy data,

F_{2}

shows an observable increase of ∼15% at high

q^{2}

for

x < 0.4

. The pattern of the increase may accommodate a threshold in

W

or new theoretical parametrizations.
