Abstract Properties of the ground state of 178Hf and the isomeric state 178Hfm2 are studied within the adiabatic and diabatic constrained relativistic mean field (RMF) approaches. The RMF calculations reproduce well the binding energy and the deformation for the ground state of 178Hf. Using the ground state single-particle eigenvalues obtained in the present calculation, the lowest excitation configuration with Kπ=16+ is found to be ν(7/2-[514])-1(9/2+[624])1 π(7/2+[404])-1(9/2[514])1. Its excitation energy calculated by the RMF theory with time-odd fields taken into account is equal to 2.801MeV, i.e., close to the 178Hfm2 experimental excitation energy 2.446MeV. The self-consistent procedure accounting for the time-odd component of the meson fields is the most important aspect of the present calculation.
