**Abstract:**

*We derive an approximate analytical formula for the K-shell ionization in collisions of very heavy atoms. The impact parameter and bombarding energy dependence are well described. The binding energy of the bound state at closest approach enters in a simple way, which could provide an experimental method for a spectroscopy of quasimolecular states. © 1978 Springer-Verlag.*
