It can be created as a doubly negatively charged ion in vacuum, which has raised the question of whether it is stable or meta stable. In this thesis we use a simple model to calculate the lifetime of the C2-60 molecule. Through tunneling calculations, it is found that the lifetime should be measurable if the dianions can be stored for up to a minute.engHow stable are molecular dianions?text
