English AbstractThe dalitz plot of eta' -> eta pi(+)pi(-) decay is studied using (225.2 +/- 2.8) x 10(6) j/psi events collected with the besiii detector at the bepcii e(+)e(-) collider. with the largest sample of eta' decays to date, the parameters of the dalitz plot are determined in a generalized and a linear representation. also, the branching fraction of j/psi -> gamma eta' is determined to be (4.84 +/- 0.03 +/- 0.24) x 10(-3), where the first error is statistical and the second systematic.
