Аннотация: New double magic nucleus 96Zr has been found out on the base of systematical joint analysis of nucleon single-particle subshells energy positions and occupation probabilities. The behavior of its “magicity” parameters - energy Е(21+) of the first 2+ state, ratio Е(41+)/Е(21+) and nucleus quadrupole deformation parameter beta2. Is typically resonance liked. It was pointed out that in Zr there are two closed subshells with the identical moment j = 5/2 (i.e. pi1f5/2 and nu2d5/2) near to Fermi energy and in addition above one of them, pi1f5/2, there is the closed subshell with j = 1/2, pi2p1/2. Many new magic nuclei (characterized by typical “magicity” parameters behavior) were revealed by application of 96Zr subshell structure features scheme (an empirical rule) to other subshells. On the whole many nuclei (14C, 14,16,24,28,40,48O, 26,28,30Si, 30,32S, 52,54Ca, 90,92,94,96Sr, 92,94,96,98Zr) can be treated as new magic ones because of the empirical rule under discussion conditions existence and “magicity” parameters behavior. That empirical rule can be attributed to additional specific attractive proton-neutron interaction – n-p-pairing
