| Outline of Final Research Achievements |
To synthesis of superheavy elements, the shell structure is very important not only in the stability of nuclei, but also the fusion process, especially the cold fusion reaction. We employ the Langevin equation with the microscopic transport coefficients and calculate the fusion cross section for the reaction 70Zn+ 208 Pb as a test. We found the enhancement of the fusion probability due to the small friction. In the dynamical process, the effect of nuclear structure is investigated precisely. We suggest new approach for synthesis of superheavy elements.

| Academic Significance and Societal Importance of the Research Achievements |
人類の文明の発展を支えてきた元素発見の歴史は、現在も続いており、科学文明の根幹をなしている。数年前に日本由来の元素であるニホニウムが周期表に加わり、非常に大きな話題になった。新元素が発見され周期表に新しい名前が加わることは小学生にも理解することができる最先端の科学ニュースである。知的好奇心だけではなく、原子力エネルギーの話題、さらに国際間の共同研究なども新元素合成には深く密接に関係している。
