The probability is calculated of generation of an electron-positron pair bу the field of а Coulomb center in а superstrong magnetic field. An equation is which defines implicitly the charge of а heavy nucleus at which а restructuring of the vacuum of electrons and positrons is initiated in Coulomb and superstrong magnetic fields (the critical charge). А function is constructed to characterize the space distribution of the electron charge in the new (charged) vacuum.
