[en] The energies, B(E2)↑, ρ² and X(EO/E2) values in ²³⁸U and ²⁴⁰Pu are calculated in the RPA at quadrupole deformation β₂ = 0.6 with the constant of quadrupole interaction which are the same as in calculations at β₂ = 0.24. The structure of the 0⁺ states in the second minimum differ from the one in the fist minimum. The pp interaction strongly effects on a structure of 0⁺ states. The calculated energies and ρ² values of the first excited 0⁺ states in ²³⁸U and ²⁴⁰Pu are in reasonable agreement with the experimental data. The isovector second 0⁺ states are predicted to appear in excitation energy 1 MeV. (author)
