Abstract
The widths for pionic decays of the lowest two excited doublets (0(+), 1(+)) and (1(+),2(+)) of heavy mesons are studied with QCD sum rules i n the leading order of heavy quark effective theory. The ambiguity due to the presence of two distinct 1(+) states is solved. The soft pion approximation is not used. [S0556-2821(98)05121-2].
