The pion play an important in recent theoretical models including the Effective Field Theory and the Constituent Quark Model with Goldstoune Exchange Interaction. Nucleon interactions within nuclei are considered as a result of one- and many-pion exchange. The role of tensor forces connected with the pion exchange in the description of nuclear binding energies and nuclear excitations was discussed recently by T.Otsuka, I.Tanihata, A.Arima and others. We performed the analysis of values of excitation in many nuclei which are situated at different parts of nuclear shells where tensor forces are important. We find out a systematic character of excitations and spacing in such nuclei by using recent compilation of nuclear excitations from Landoldt Bernstein Library vol I/25 Springer. Two the most frequently appearing stable energy excitation and intervals are found to be rationally connected with the pion and nucleon mass differences. This conclusion will be considered together with several the strongest correlations in the near-magic nuclei and in nuclei with the collective motions of nucleons.
