Abstract
Using D+ mesons exclusively reconstructed in the DELPHI detector at L EP, an excess of 66 +/- 14(stat.) events is observed in the D(+)pi(+) pi(-) final state with a mass of 2637 +/- 2(stat.) +/- 6(syst.) MeV/c( 2) and a full width smaller than 15 MeV/c(2) (95% C.L.). This signal i s compatible with the expected decay of a radially excited D' (J(P) = 1(-))meson.
