Ionization Energy Database

The DREEBIT Ionization Energy Database app provides information about the energy which is necessary for ionization of an atom or ion of a certain chemical element, i.e. to extract an electron from a specific shell in the electrostatic potential of its nucleus. Furthermore, the overall potential energy stored in the selected ion is given.

HCI Database App

The DREEBIT HCI Database app provides information about the ionisation energy of highly charged ions. The lists of elements and possible charge states can be filtered by typing in the input field.
