The calculations of the ground state properties of even-even nuclei with extreme neutron excess, far away from the well-known neutron stability boundary (SOT), were carried out. The calculations are based on the Hartree - Fock method using with Skyrme forces, taking into account the axial deformation and pairing in the BCS approximation. It is shown that the chain of isotones with neutron number N = 126 outside SOT peninsula forms stable nuclei (PIC) with respect to the emission of one neutron. Obtained results for long chains of isotopes Zr and Pd to STS are then compared with the results of Hartree-Fock-Bogolyubov. Depending on the square of the invariant mass of the lepton pair the relative decay width and different CP-asymmetries were calculated. The calculations can be useful in the analysis of experimental data and in the design of experiments to search for new physics effects.
