Abstract Using gaseous60CoI2 sources, the velocity distribution of60Ni nuclei afterβ-decay of60Co has been measured by the nuclear-resonance-fluorescence coincidence (NRFC) method. By comparison with model calculations, information is obtained on the rearrangement of electrons on the molecule as a consequence of the change of nuclear charge. In 42% of the rearrangement processes bound (NiI2)+ or (NiI)+ molecule ions are formed. In 24% the molecule is singly charged but with the bonds between Ni and its molecular partners ruptured. In 34% the charging of more than one molecular partner leads to Coulomb explosion of the molecule. The probability of finding more than one charge on the molecule is larger by a factor of 2 as compared to the probability for electron shake-off on an isolated Ni atom.
