dc.description.abstract	Using D∗+ mesons exclusively reconstructed in the DELPHI detector at LEP, an excess of 66±14(stat.) events is observed in the D∗+π+π− final state with a mass of 2637±2(stat.)±6(syst.)~MeV/c2 and a full width smaller than 15~MeV/c2 (95\% C.L.). This signal is compatible with the expected decay of a radially excited D∗′ (JP=1−) meson.
