【 摘 要 】

The role of the nuclear charge screening and correctness of Born approximation for electron which is leaving atomin the process of atomic ionization at annihilation of positron with another electron of daughter's atom at β+-decay isstudied. Processes of the different atomic shells ionization at annihilation of positron, emitted at β+-decay, with Kelectronof daughter's atom are considered. It is shown that the screening effect is important only for shell with n = 4.While corrections to the Born approximation plays the essential role for all shells. It is shown that the most probableprocess is related with emission of other K-electron.
