Tóm tắt

Hạt nhân siêu nặng 256Rf, nơi đã quan sát thấy dải quay và đồng vị đa-quasi hạt, đã được nghiên cứu bằng cách sử dụng các phép tính mặt phẳng Routhian tổng và các phép tính ràng buộc cấu hình của mặt phẳng năng lượng tiềm năng, với sự bao gồm của biến dạng β 6. Mô men quán tính thực nghiệm được tái tạo tốt, cho thấy rằng sự căn chỉnh bị chậm lại do biến dạng β 6. Một trạng thái K π = 5− hoặc 8− có thể hình thành một đồng vị hai-quasi hạt được tính toán có rào cản phân hạch cao hơn so với trạng thái cơ bản.
