Abstract
The 1s bound state of superheavy atoms and molecules reaches a binding energy of at . It is shown that the shell is still localized in space even beyond this critical proton number and that it has a width (several keV large) which is a positron escape width for ionized shells. The suggestion is made that this effect can be observed in the collision of very heavy ions (superheavy molecules) during the collision.
