Summary
The charge densities of the zirconium isotopes 90, 92 and 94 are calculated by summing the squares of the proton wave functions in a one-body potential whose parameters are adjusted to give the experimental centroid energies. The squared wave functions are weighted by the single-particle occupation numbers. Accurate fits are obtained to the charge densities, and their differences are interpreted in terms of a simple model. It is also found that the radii of the potentials show significant departures from theA 1/2 variation along the isotopic sequence.
Riassunto
Si calcolano le distribuzioni di carica degli isotopi90Zr,92Zr e94Zr, sommando i quadrati delle funzioni d’onda dei protoni costruite in un potenziale ad un corpo i cui parametri sono fissati in modo da riprodurre i valori sperimentali per i centroidi delle energie di singola particella. I quadrati delle funzioni d’onda sono pesati sui rispettivi numeri di occupazione. Le densità di carica sono riprodotte in modo soddisfacente e le loro differenze interpretate tramite un semplice modello. Si trova inoltre che nella sequenza isotopica i raggi del potenziale si discostano dalla legger 0 A 1/2.
Резюме
Вычисляются плотности зарядов изотопов циркония 90, 92 и 94, суммируя квадраты волновых функций протона в одночастичном потенциале, параметры которого подгоняются, чтобы дать экспериментальные энергии центроида. Квадраты волновых функций входят с весами, определяемыми числами одночастичных заполнений. Получается аккуратная подгонка для плотностей заряда и их разности интерпретируются в терминах простой модели. Также получено, что радиусы потенциалов обнаруживают существенные отклонения от зависимостиA 1/2 вдоль изотопической последовательности.
