Summary
A method of stabilized analytic continuation, designed for the purpose of extending approximate data, is described and is used to investigate the resonance structure of a quantum-mechanical Green’s function, for which an exact solution is known. The model provides evidence for the effectiveness of the method employed.
Riassunto
Si descrive un metodo di continuazione analitica stabilizzata, concepita allo scopo di estendere i dati approssimati, e lo si usa per studiare la struttura di risonanza di una funzione di Green quanto-meccanica, per la quale si conosce una soluzione esatta. Il modello fornisce la prova dell’efficacia del metodo usato.
Реэюме
Описывается метод аналитического продолжения, предложенный для уточнения приближенных данных. Этот метод испольэуется для исследования реэонансной структуры квантовомеханичес кой функции Грина, для которой иэвестно точное рещение. Предложенная модель подтверждает зффективность испольэуемого метода.
