Abstract. In this first of a series of papers, the groundstate of a
nonrelativistic atom, minimally coupled to the quantized radiation
field, and its groundstate energy are constructed by an iteration
scheme inspired by work of Pizzo. This scheme successively
removes an infrared cutoff in momentum space and yields a convergent
algorithm enabling us to calculate the groundstate and the
groundstate energy, to arbitrary order in the feinstructure constant.
