Suppression of false resonances in the resonating-group method

Подавление ложных реэонансов в методе « реэонируюшей группы »

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

It is shown in a numerical example that false resonances arise in the resonating-group method when an open channel is neglected. They can be suppressed by a least-squares defect minimization method which has been developed recently.

Riassunto

Si dimostra con un esempio numerico che nel metodo dei gruppi risonanti si manifestano false risonanze qualora si trascuri un canale aperto. Tali risonanze si possono eliminare facendo uso di un metodo, recentemente sviluppato, di minimizzazione dei difetti dei minimi quadrati.

Реэюме

На численном примере покаэывается, что ложные реэонансы поя-вляются в методе « реэонируюшей группы », когда пренебрегается открытым каналом. Ложные реэонансы могут быть подавлены благодаря методу минимиэации дефектов по методу наименьщих квадратов, который был раэвит в последнее время.
