On the Reliability of Microscopic Optical Model Calculations — •Helmut Leeb, Marco Pigni, and Imante Raskinyte — Atominstitut of Austrian Universities, TU Wien, Wiedner Hauptstrasse 8-10, A-1040 Wien, Austria

The optical model is a basic ingredient for many calculations of nuclear reaction cross sections. Several so-called microscopic optical potentials are available which yield a fair reproduction of the gross structure of the corresponding scattering observables. At present there is an increased demand from nuclear technology for a reliable quantitative estimate of such model calculations. In this contribution we present a procedure to estimate quantitatively the uncertainties of such model calculations. The reliability of the method is checked via a comparison of microscopic optical model calculations with recent experimental nucleon-nucleus scattering data.
