超重元素合成是当今核物理研究的热点。至今,利用~(48)Ca轰击锕系靶核引起的热熔合,“超重岛”已延伸到Z=118号元素。然而,目前所有合成的超重核都位于“超重岛”的丰质子一侧。为了达到“超重岛”的中心区域,将来需利用高束流强度的丰中子放射性束。因此,蒸发残余截面的 Overweight element synthesis is the hot point of nuclear physics research. To date, the thermal fusion caused by actinide target nuclei has been bombarded with ~ (48) Ca, and “excess island” has been extended to element Z = 118. However, all currently synthesized super-heavy nuclei are located on the abundance proton side of the “hyper-heavy island”. In order to reach the center of the “overweight island”, it is necessary to use a high-beam neutron beam of high beam intensity in the future. Therefore, the evaporation of the residual section
