<jats:title>Abstract</jats:title><jats:p>For narrow band metals the distortions of the form of X‐ray and X‐ray photoelectron spectra are investigated under the influence of the vacancy on the inner level. A calculation method over the whole energy interval of the distoring influence of the hole field is proposed and realized numerically. The site formalism is developed to describe the X‐ray spectra. Equations are obtained in the energetic representation which allow to effect a numerical analysis.</jats:p>
