摘要:

除了正确选择入射通道外,选择最佳束流能量对超重元素的合成起着至关重要的作用。用先进的统计和双核系统模型对成功合成Z=104-118和失败的Z=119-120超重元素的所有实验进行了深入的研究,我们推断,束流能量的不当选择可能是导致产生截面太小而无法测量的原因,从而导致崩溃。对Z=104-120的超重元素,我们预测了获得最大产生截面的最佳束流能量。希望利用这些预测可能很快就会将周期表延长到第八周期

英文摘要:

Besides right choice of entrance channel, selection of optimal beam energies for synthesis of superheavy elements plays a crucial role. A thorough investigation with the advanced statistical and dinuclear system models on all the experiments performed for the synthesis of the successful superheavy elements Z=104-118 and failed superheavy elements Z=119-120 leads us to infer that improper choice of the beam energies may be responsible for too low production cross sections to measure and thus the cause for the debacle. We have predicted the optimal beam energies to obtain the maximum production cross sections for all the reactions used for the superheavy elements Z=104-120. Hope exploitation of these predictions may be on the cards soon to extend the periodic table for the eighth period
