Abstract
Production of higher harmonics in a model atom described by a three-dimensional δ-function potential in the presence of a monochromatic linearly polarized field is investigated. The rates for production of the individual harmonics can be expressed as one-dimensional integrals. The only property of the atom that enters the model is its ionization energy. The results are in qualitative agreement with many of the data. In particular, the model exhibits a ‘‘rising plateau.’’Keywords
