Role of Deuteron NN^* -components in proceses pd - dp and pd- dN^*

The contribution of nucleon isobar $N^*$ exchanges to backward elastic pd-scattering is calculated on the basis of deuteron 6q-model and found to be negligible in comparison with the neutron exchange. It is shown that the pole amplitude of neutron pickup from the deuteron $nN^*$-component is favoured in the reaction $pd\to dN^*$ for backward going $N^*(1440)$ and $N^*(1710)$ at kinetic energy of incident proton of 1.5--2 GeV whereas the triangular diagram with subprocess $pp\to d\pi^+$ related to the usual $pn-$component of deuteron is considerable suppressed.
