摘      要：K-shell ionization for Li-like uranium ions in collisions with a N2 target was performed at the ESR storage ring. We found surprisingly that in such close encounters the 2 s electron remain almost unaffected by the collisions. A dedicated experimental study was conducted by using Li-like uranium ions at an initial energy of 378 MeV/u in order to manifest the situation. In Fig.1 a typical spectrum is shown registered by a Ge(i)
