| Abstract: | Cross sections for production of the therapeutic radioisotope 131Cs via the 133Cs(p,3n)131Ba→131Cs route were investigated at cyclotrons. Excitation functions of the 133Cs(p,x)133m,133mg,131mg,129g,129m,128Ba, 132,129cum,127cumCs and 129m(ind),127cum,125cumXe nuclear reactions were measured up to 70 MeV proton energy. The experimental data were compared to the results of model calculations performed by means of ALICE-IPPE, EMPIRE-II and TALYS computer codes. Good overall agreement was observed. On the basis of the measured excitation functions integral yields were deduced. Charged particle production routes of 131Cs are discussed. |
