Summary
A flexible parametrization of local-density distributions in nuclei is suggested on the basis of local-scale point transformations performed on certain model many-particle wave functions. The new set of local densities can be helpful in many problems in nuclear physics. Two examples are considered: i) an analysis of experimental elastic electron scattering data and ii) variational calculations with effective interaction for reproducing the Hartree-Fock shell oscillations of the local-density distributions.
Riassunto
Si suggerisce una parametrizzazione flessibile delle distribuzioni di densità locale nei nuclei sulla base di trasformazioni puntuali di scala locale effettuate su alcune funzioni d'onda teoriche a molte particelle. Il nuovo insieme di densità locali può essere utile in molti problemi di fisica nucleare. Si considerano due esempi: un'analisi dei dati sperimentali dello scattering elastico degli elettroni e i calcoli variazionali con interazione efficace per riprodurre le oscillazioni di strato di Hartree-Fock delle distribuzioni di densità locale.
Резюме
Предлагается универсальная параметризация распределений локальной плотности в ядрах на основе преобразваний, вьшолненных с помощью модельных много-частичных функций. Новая система локальных плотностей может быть полезной в многих проблемах в ядерной физике. Рассматриваются два примера: 1) анализ экспериментальных по упругому рассеянию электронов и 2) вариационные вычисления с эффективным взаимодействием для воспроизведения оболочечных осцилляций Харти-Фока распределений локальной плотности.
