This paper presents a search for the t-channel exchange of an R-parity violating scalar top quark ({tilde t}) in the e{sup {+-}} {mu}{sup {-+}} continuum using 2.1 fb{sup -1} of data collected by the ATLAS detector in {radical}s = 7 TeV pp collisions at the Large Hadron Collider. Data are found to be consistent with the expectation from the Standard Model backgrounds. Limits on R-parity-violating couplings at 95% C.L. are calculated as a function of the scalar top mass (m{sub {tilde t}}). The upper limits on the production cross section for pp {yields} e{mu}X, through the t-channel exchange of a scalar top quark, ranges from 170 fb for m{sub {tilde t}} = 95 GeV to 30 fb for m{sub {tilde t}} = 1000 GeV.
