This research involves the formation, investigation and manipulation of the highly unusual molecular states formed due to collisions between highly-excited atoms. The principal molecule of interest comprises a positively-charged and negatively-charged ion (a cation and anion) orbiting each other with a separation approximately 10,000 times greater than is normally found between atoms in typical molecules. Due to their unique size and slow rate of evolution compared to typical atoms and molecules, these molecules are ideal tools with which to interrogate the fascinating boundary between the classical and quantum worlds. To date they have been observed in only a few species using a complicated and inefficient train of optics, and much remains unknown about their formation. We intend to determine precisely how these novel molecules are formed and learn more about the underlying science, which could subsequently allow the production of large numbers of these molecules for future, groundbreaking, investigations.

这项研究涉及由于高激发原子之间碰撞而形成的极不寻常分子状态的形成、研究和操纵。感兴趣的主要分子包括带正电荷和带负电荷的离子（阳离子和阴离子），它们以比在典型分子中的原子之间通常发现的间隔大大约10，000倍的间隔彼此绕轨道运行。由于与典型的原子和分子相比，它们独特的尺寸和缓慢的进化速度，这些分子是询问经典和量子世界之间迷人边界的理想工具。到目前为止，它们只在少数几个物种中被观察到，使用了一种复杂而低效的光学系统，而且关于它们的形成还有很多未知之处。我们打算精确地确定这些新分子是如何形成的，并了解更多关于基础科学的信息，这可能随后允许生产大量这些分子，用于未来的开创性研究。
