| 摘 要： | Tensor Polarization t20 of the deuteron is calculated on the basis of a hybrid quark-hadron model.A relativistic wavefunction of the deuteron is used to calculate the relativistic impulse approximation and the contribution of the ρπγ meson exchange process.A good agreement with experimental data is achieved when and only when the ρπγ coupling is taken as positive.
