Isomeric ratios were measured for (γ, n) and (n, γ) reactions on Eu isotopes, which lie at the boundary between spherical and deformed nuclei. Targets from ¹⁵¹Eu and ¹⁵³Eu were irradiated by thermal neutrons and by bremsstrahlung photons from a microtron with endpoint energies between 13 and 22 MeV. The reactions under investigation resulted in the excitation of 0^- and 8^- isomeric states in ¹⁵⁰Eu, ¹⁵²Eu, and ¹⁵⁴Eu isotopes. The γ spectra of product nuclides were measured to determine the reaction yields. The effect of quadrupole deformation on the isomeric ratios is discussed.
