Abstract
We present model independent measurements of the helicity basis form factors in the decay D+→K-π+e+νe obtained from about 2800 decays reconstructed from a 281pb-1 data sample collected at the ψ(3770) center-of-mass energy with the CLEO-c detector. We confirm the existence of a previously observed spin-zero K-π+ component interfering with the K̄*0 amplitude. We see no evidence for additional d- or f-wave contributions.
