Abstract

The $P$ and $T$ odd deuteron multipoles are calculated in the Reid nucleon-nucleon potential in the chiral limit $m_{\pi}\to 0$. The contact current generated by the $\pi$-meson exchange does not contribute to the anapole moment. The contact current generated by the vector meson exchange is negligible in comparison with other contributions of vector mesons. The result for the deuteron electric dipole moment is of great interest because of the experiment on its measurement discussed in Brookhaven. The deuteron photodisintegration cross section asymmetry at the threshold is also calculated. It is shown that its value strongly depends on the tensor forces and d-wave contribution to the deuteron wave function.
