Kopsavilkums

The effect of pulsed electron irradiation on the long- and short-range order in the La_0.7Sr_0.3CoO₃ ceramics is reported. Neutron and X-ray powder diffraction reveal that the unit cell symmetry and single-phase state of single and multiple irradiated La_0.7Sr_0.3CoO₃ are preserved, while the oxygen atoms coordination changes towards the La_0.5Sr_0.5CoO₃ structure. X-ray absorption data confirm this observation and further reveal the details of the shift and splitting of the Co³⁺ t_2g and e_g atomic orbitals. Possible mechanisms of pulsed electron irradiation effect in La_0.7Sr_0.3CoO₃ are discussed.
