This project aims to measure properties, probabilities and timescales of competing quasifission processes, by combining Australian accelerator and detector capabilities with exotic radioactive targets. In 2015, nuclear fusion created superheavy elements with atomic numbers 113 to 118. The race is now on to create elements 119 and 120, as their production and properties should pin down the location of the predicted superheavy Island of Stability, but 3-fragment quasifission is a major impediment to their formation. This project will evaluate quassification processes on the nuclear reactions proposed to form new superheavy elements and is expected to identify the best reactions for their discovery. The synthesis of new elements tests quantum physics, relativistic chemistry and element creation in the cosmos, and offers high profile returns on investments.

该项目旨在通过将澳大利亚加速器和探测器能力与外来放射性目标相结合，测量相互竞争的准裂变过程的性质、概率和时间尺度。2015年，核聚变创造了原子序数在113到118之间的超重元素。创造第119号和第120号元素的竞赛现在正在进行，因为它们的生产和性质应该可以确定预测的超重稳定岛的位置，但3碎片准裂变是它们形成的主要障碍。该项目将评估核反应的量化过程，以形成新的超重元素，并有望确定发现这些核反应的最佳反应。新元素的合成测试了量子物理、相对论化学和宇宙中的元素创造，并提供了高调的投资回报。
