Due to significant systematical errors of the experimental nuclear spectroscopy data obtained by different methods one is often forced to deal with very discrepant data. To remove the systematical errors and increase data accuracy and reliability, new data-processing technologies were developed. One can obtain also new information that has not (could not) been obtained before. It is shown that energies of the first 2+ levels in Zr isotopes can be explained in the framework of the shell-model approach. A separation of 2d5/2 subshell in 96Zr (like 1f7/2 subshell in 48Ca) is found, so the neutron number N = 56 becomes like a magic number for Z = 40. To explain a similarity in decay properties of 48Ca and 96Zr an additional interaction between closed structures consisting of 20 and 28 nucleons is proposed. Irregularities in the ground-state spin values in K isotopes are explained by the inversion of the proton 1d3/2 and 2s1/2 orbitals.
