THẾ QUANG HỌC VỚI TƯƠNG TÁC SKYRME CHO TÁN XẠ NEUTRON TRÊN OXYGEN-16 TẠI NĂNG LƯỢNG THẤP
Main Article Content
Abstract
Các tính toán Hartree-Fock (HF) sử dụng thế tương tác nucleon-nucleon hiệu dụng Skyrme để mô tả cấu trúc hạt nhân đã và đang được áp dụng rộng rãi trong vật lý hạt nhân. Trong công trình này, chúng tôi nhấn mạnh khả năng áp dụng của các tính toán đó để mô tả tán xạ đàn hồi ở năng lượng thấp. Sử dụng thế quang học thu được từ tính toán trường trung bình HF với tương tác Skyrme SkM* và SLy4, chúng tôi tính độ lệch pha và tiết diện tán xạ trong quá trình tán xạ neutron trên hạt nhân 16O. Các kết quả thu được cho thấy khả năng của phương pháp trong việc xác định cộng hưởng ở năng lượng thấp.
