Summary
The natural orbital representation in the single-particle potential method is applied to calculate the proton momentum distribution in40Ca. The dependence of the momentum and density distributions on different sets of occupation numbers is examined, and the results are compared with calculations using other theoretical models including nucleon-nucleon correlations.
Riassunto
Si applica la rappresentazione orbitale naturale al metodo del potenziale a particella singola, per calcolare la distribuzione dell’impulso del protone in40Ca. Si esamina la dipendenza delle distribuzioni dell’impulso e della densità da diversi insiemi di numeri di occupazione e i risultati sono confrontati con i calcoli usando altri modelli teorici, comprese le correlazioni nucleone-nucleone.
