Description

Results of the sudden approximation are compared to predictions of the conventional DWBA and to experiment. The asymptotic spectroscopic amplitude obtained by the sudden approximation is interpreted as the maximum limit of its true value. The main approximations of the model are asserted to stem from violations of the completeness of the virtual neutron wavefunctions and the crude application of the sudden approximation. It appears impossible to separate these two points. Improvements of the model are discussed. (orig.)

Abstract (German)

Ergebnisse der 'sudden approximation' werden mit Vorhersagen der herkoemmlichen DWBA und mit experimentellen Ergebnissen verglichen. Die durch die 'sudden approximation' erhaltene asymptotische spektroskopische Amplitude wird als Hoechstgrenze ihres Absolutwerts interpretiert. Die Hauptnaeherungen des Modells stammen aus Verletzungen der Vollstaendigkeit der virtuellen neutronen Wellenfunktionen und der nichtzentralen Anwendung der 'sudden approximation'. Diese beiden Punkte scheinen untrennbar. Verbesserungen des Modells werden diskutiert. (orig./AK)
