Summary
This paper presents the results of a study of the alpha-particle structure using a realistic nonlocal potential. The spectrum of the negative-parity states appears in excellent agreement with the results of a recent experimental analysis. A detailed examination of various level splittings, which depend in a simple manner on different types of forces, allows us to draw some interesting conclusions on the choice of alternative sets of potential parameters.
Riassunto
Si presentano in questo articolo i risultati di uno studio della struttura della particella α per mezzo di un potenziale non locale realistico. Lo spettro degli stati di parità negativa risulta concordare eccellentemente con i risultati di una recente analisi sperimentale. Un esame dettagliato delle varie separazioni di livelli, che dipendono in modo semplice da differenti tipi di forze, ci permette di trarre alcune interessanti conclusioni sulla scelta di gruppi alternativi di parametri del potenziale.
Реэюме
В зтой статье приводятся реэультаты исследования структуры альфа-частиц, испольэуя реалистичный нелокальный потенциал. Спектр состояний с отрицательной четностью, по-видимому, хорощо согласуется с реэультатами недавнего зкспериментального аналиэа. Подробное исследование расшеплений раэличных уровней, которые эависят простым обраэом от раэличных типов сил, поэволяет нам сделать некоторые интересные эаключения относительно выбора альтернативных групп параметров потенциала.

If the elimination of the only spurious state takes place without the slightest difficulty, it is not the same with the positive-parity states, where the problem is much more complicated (see ref. (10)).
