Abstract

The mass-energy distributions of fragments formed in reactions ^16,18O + ²³²Th, ²³⁸U, and ²²Ne + ²³²Th, ²³⁸U at energies near the Coulomb barrier are measured to study the role of multimodal fission in the reactions of light ions with strongly deformed actinide nuclei. It is found that at these energies, multimodal fission affects significantly the mass–energy and angular distributions of fragments that results in an increase of the width of mass distributions and large angular anisotropy as in the case of quasifission.

与形核反应的裂变和拟裂变

摘要

测量在库仑势垒附近能量处的反应^16,18 O + ²³² Th，²³⁸ U和²² Ne + ²³² Th，²³⁸ U中形成的碎片的质量能分布，以研究多峰裂变在光反应中的作用act系原子核严重变形的离子。发现在这些能量下，多峰裂变会显着影响碎片的质能和角分布，与准裂变一样，会导致质量分布宽度的增加和较大的角度各向异性。
