摘要：

The results of Hartree-Fock self-consistent field calculations show that the change of the probability of electron capture by a 7Be nucleus in excited atoms and ions, caused by the change of electron density at the nucleus, is strongly compensated by a change of opposite sign, caused by the change of exchange and overlap correction factors Bx. This compensation is responsible for the smallness of the chemical changes of the 7Be radioactive decay probability experimentally observed. © 1979.
