The cross-sections of 136Ba(p,x) nuclear reactions were measured using the stack foil technique in the energy range of 29.3 → 14.0 MeV for the first time. We compared the experimental values with the data from the TENDL-2023 library. The yields of radionuclides formed during irradiation calculated by integrating the cross-sections are: 951 MBq/(μA·h) for 135La, 12 MBq/(μA·h) for 133La, 30 MBq/(μA·h) for 135mBa, and 0.3 MBq/(μA·h) for 132Cs. It was shown that the 136Ba(p,2n)135La reaction is suitable for production of 135La for medicine in terms of activity and radioisotopic purity of the obtained product. Chromatographic separation of lanthanum radioisotopes from barium target was carried out using the TRU resin sorbent.
