In the doubly magic nucleus states at excitation energies MeV populated by the inelastic proton scattering via the doublet isobaric analog resonances g +d in are studied. Sixteen states containing dominant strengths of the configurations g p , d p , g f , d f are newly assigned spins from to , among them ten states are newly identified. Amplitudes with relative signs of up to four one-particle one-hole configurations with strengths down to 0.05% are determined in 40 states with spins from 1 to . Amplitudes of configurations d p , d p , d f for fourteen states and amplitudes of g p , g p , g f for twenty-seven states are determined. Total strengths up to the full strength are found for configurations d p , d p , d f with spins from to and for g p , g p , g f with spins from 1 to .
