Summary
We discuss the influence of the short-range correlation on the charge distribution and elastic charge from factor of4He and present the numerical results. The charge density oscillates at the centre of the nucleus as higher-order terms from the cluster expansion are included. The second minimum and the third maximum are produced in the charge form factor with the fully correlated wave function or when sufficiently higher-order terms are included in the calculations.
Riassunto
Si esamina l'influenza della correlazione a corto raggio sulla distribuzione di carica e il fattore di forma elastico della carica dell'4He e si presentano i risultati numerici. La densità di carica oscilla al centro del nucleo mano a mano che dall'espansione a gruppi si includono termini di ordine sempre maggiore. Si producono il secondo minimo e il terzo massimo nel fattore di forma della carica con la funzione d'onda interamente correlata o quando si includono nei calcoli termini di ordine sufficientemente piú alto.
Резюме
Мы обсуждаем влияние короткодействующей корреляции на зарядовое распределение и упругий форм-фактор заряда для4He. Приводятся численные результаты. Плотность заряда в центре ядра осциллирует, когда включаются члены высших порядков кластерного разложения. Воспроизводятся второй минимум и третий максимум в форм-факторе заряда с полностью коррелированной волновой функцией, или когда включаются в вычисления достаточно высокие члены разложения.
