Abstract

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.
