系统地研究了丰中子弹与238U靶的热聚变反应产生Z = 108−116的超重核。结果表明，超重核的产生截面并不随原子序数Z的增加而单调减小。在Z = 112和115处的超重核反应截面比合成超重核时的全Z趋势有所增强，这清楚地说明具有大负Q值和壳层修正的反应更有利于合成超重核。
The production of superheavy nuclei withZ= 108−116 via hot fusion reactions of the neutron-rich projectiles with238U target is systematically studied. The results show that the production cross sections of superheavy nuclei do not decrease monotonously as the atomic numberZincreasing. The cross sections of the superheavy nuclei atZ= 112 and 115 are enhanced as compared with the wholeZ-trend in synthesis of the superheavy nuclei, which clearly illustrates that the reactions with large negativeQ-value and shell correction are more favorable to synthesize superheavy nuclei.
