Ключові слова:

потенцiал взаємодiї мiж ядрами, модифiкований метод Томаса–Фермi, розподiл густини нуклонiв, поперечний перерiз, кор вiдштовхування, пружне розсiяння

Анотація

Густини розподiлу нуклонiв та потенцiали взаємодiї мiж ядрами для реакцiй 16O + 40Ca, 16O + 56Fe та 16O + 90Zr було розраховано в рамках модифiкованого методу Томаса–Фермi, з урахуванням усiх доданкiв до членiв другого порядку по ~ у квазикласичному розкладi кiнетичної енергiї. В якостi нуклон-нуклонної взаємодiї використовувалися сили Скiрма, залежнi вiд густини нуклонiв. Знайдено параметризацiю потенцiалу взаємодiї мiж ядрами, яка добре описує величину потенцiалу, розрахованого у рамках модифiкованого пiдходу Томаса–Фермi з залежними вiд густини силами Скiрма. На основi одержаних потенцiалiв було обраховано перерiзи пружного розсiяння, що добре узгоджуються з експериментальними даними.
