Join us in welcoming Prof Gerard Meijer to talk about thermionic emission, autoionization and associative ionization.
Some molecules have the unusual property that their dissociation energy is larger than their ionization energy. Their cations can be efficiently formed via the unique and often overlooked processes mentioned in the title. I will show that his offers new possibilities for the production of cold molecular ions and that it can explain the mere presence and relative abundance of several peculiar species in the outflows of stars.
