Experiments have shown major failings of our best predictive model of nuclear fusion. This project will address these failings through a multifaceted research program which will develop and benchmark an enhanced quantum model and test for missing physics by conducting precision fusion measurements for carefully chosen reactions. This project will develop a new technique that exploits fission following fusion to directly probe physical processes inside the fusion barrier, which are missing from current models. This integrated approach to fusion will allow us to better predict fusion cross sections, create new elements and exploit radioactive ion beams at new international facilities.

实验表明，我们最好的核聚变预测模型存在重大缺陷。该项目将通过一个多方面的研究计划来解决这些问题，该计划将开发和基准测试增强的量子模型，并通过对精心选择的反应进行精确的聚变测量来测试缺失的物理学。该项目将开发一种新技术，利用聚变后的裂变直接探测聚变屏障内的物理过程，这是目前模型所缺少的。这种融合的综合方法将使我们能够更好地预测融合横截面，创造新的元素，并在新的国际设施中利用放射性离子束。
