摘要：

Heavy-quark symmetry relates the D-wave amplitude for D1(2420) --> D* pi to the amplitudes for the decays D2* (2460) --> D* pi and D2* (2460) --> D-pi. We discuss the extraction of the S and D partial wave amplitudes for D1 --> D* pi and their significance as tests of the applicability of heavy-quark symmetry for charm quarks.
