dc.description.abstractIn this work, a method to introduce radioactive 140La nuclei with a half-life (t1/2) of 40.8 h, into samples of LaBaTM2O6 (TM = Mn, Co) double perovskites is described to carry out perturbed gamma-gamma angular correlation (PAC) spectroscopy measurements using 140La(140Ce) as probe nuclei. There are several methods to insert this probe nucleus in the samples and the present paper presents a new methodology to obtain the 140La(140Ce) in the compounds. These compounds were submitted to short irradiations with thermal neutrons in the rabbit station of IEA-R1 nuclear reactor of the IPEN/CNEN-SP. This method could be used because natural La is present in samples. Natural La contains the 139La isotope which, when irradiated with neutrons produces the 140La radioisotope, the parent radioisotope of 140Ce used for PAC measurements. However, other elements present in the compounds are also activated, in particular the isotopes 56Mn, 139Ba and 60mCo. In order to verify if these radioisotopes are presents in the PAC measurements, the gamma ray spectra of these irradiated samples can be measured at different decays times using a high resolution HPGe spectrometer. Samples were irradiated with thermal neutrons for 3 minutes. After short irradiation, the gamma ray spectra were acquired, one hour, 18 h, 24 h and 48 h after irradiation. The gamma ray energies of 328.8 keV and 487.0 keV of 140La (measured in the PAC spectroscopy) can be identified. Besides this, gamma-rays peaks of 56Mn (Eγ of 847.3 and 1812.9 keV and t1/2 of 2.57 h), 139Ba (Eγ of 166.04 keV and t1/2 of 84.63 min) and 60mCo (Eγ of 58.75 and 1333.30 keV and t1/2 of 10.47 min) are identified too. The results indicate that PAC measurements can be started after at least 48 h of decay time when there is in interference of other radioisotopes.pt_BR
