Nonlocal forces and hartree-fock calculations

Нелокальные силы и вычисления Хартри-Фока

Summary

A new form of the two-body potential recently proposed has been investigated for its possible applications in nuclear calculations. This nonsingular force, chosen for its success in fitting scattering phase shifts, saturates nuclear matter at the correct energy and density, and yields small second-order corrections. It can thus be applied with confidence to Hartree-Fock calculations of finite nuclei. We study the closed-shell nuclei16O and40Ca and show that many of their basic properties can be reasonably predicted.

Riassunto

Si è studiata una nuova forma del potenziale a due corpi recentemente proposta, in vista delle sue possibili applicazioni nei calcoli nucleari. Questa forza non singolare, scelta per il suo successo nell’approssimare gli spostamenti di fase dello scattering, satura la materia nucleare all’energia e densità corrette, e fornisce piccole correzioni del secondo ordine. La si può così applicare con fiducia ai calcoli di Hartree-Fock dei nuclei finiti. Si studiano i nuclei a strato chiuso16O e40Ca e si dimostra che molte delle loro proprietà fondamentali possono essere ragionevolmente previste.

Реэюме

Исследуется новая форма недавно предложенного двух-частичного потенциала для воэможных приложений в ядерных вычислениях. Эта несингулярная сила, выбранная эа счет успещной подгонки сдвигов фаэ рассеяния, насышает ядерное вешество при правильной знергии и плотности, а также дает малые поправки второго порядка. Таким обраэом, зта сила может быть применена с уверенностью в вычислениях Хартри-Фока для конечных ядер. Мы исследуем ядра с эамкнутыми оболочками16O и40Ca и покаэываем, что многие иэ их основных свойств могут быть раэумно предскаэаны.
