Some aspects of the random impurity problem in crystals are studied. A method of dealing with substitutional impurities having large defect spaces is given. The expressions found are derived within the singleโsite scattering approach and are exact to c. The effect of โlocalโ force constant changes is also considered.

We apply the effective field theory approach to the three-nucleon system. In particular, we consider S = 1/2 neutron-deuteron scattering and the triton. We show that in this channel a unique nonperturbative renormalization takes place which requires the introduction of a single three-body force at l
