and Bjorken variable x. We find new expressions for the
structure functions F1, F2, and F3 that depend on the
target mass and agree with the spectral property. We demonstrate
that these new expressions, which take mass corrections into
account for the structure functions, lead to results that differ
significantly from the results obtained both using the standard method and using the method suggested by
Steffens-Melnitchouk, especially for values Q2 of the order of
several GeV2 and for large values of x.
