Tóm tắt

Một bộ thông số tiềm năng quang học hiện tượng toàn cầu mới đã được xác định cho hạt bắn heli-3, bằng cách đồng thời điều chỉnh các dữ liệu thực nghiệm về tiết diện phản ứng tổng và phân bố góc tán xạ đàn hồi trong khoảng khối lượng của hạt nhân mục tiêu 20⩽A⩽209 tại các năng lượng bắn vào dưới 250 MeV. Một so sánh đã được thực hiện giữa các thông số tiềm năng quang học toàn cầu của heli-3 và các thông số hiện có. Các kết quả tính toán về tiết diện phản ứng tổng và phân bố góc tán xạ đàn hồi cũng được so sánh với dữ liệu thực nghiệm với sự phù hợp thỏa đáng.
