Abstract
For the first time the reaction pp-->d pi(+) was measured close to thr eshold. A magnetic spectrometer (3Q2DQ) which allows ray tracing was a pplied to detect the recoiling deuterons and reconstruct their momenta . The measured anisotropies are between 0.008 and 0.29, indicating the importance of p-wave amplitudes even close to threshold. The presente d data support the validity of isospin and time reversal symmetries.
