Abstract
We calculate the electric dipole moments of the neutron and the Lambda with in the framework of heavy baryon chiral perturbation theory. They are induc ed by strong CP-violating terms of the effective Lagrangian in the presence of the vacuum angle theta(o). The construction of such a Lagrangian is out lined and we are able to give an estimate for theta(o).
