The aim of the present work was to study the cross-section of the (n,2n) reaction on 203 Tl, by irradiating a natural TlCl pellet target with monoenergetic neutron beams at 16.4, 18.9 and 19.3 MeV. The cross section of the 203 Tl(n,2n) 202 Tl reaction was measured via the activation method, with respect to the 197 Au(n,2n) 196 Au and 27 Al(n,α) 24 Na reference reactions. At the same time, the 203 Tl(n,3n) 201 Tl was also measured at 18.9 and 19.3 MeV. The monoenergetic neutron beams were generated at the 5.5 MV Tandem accelerator of NCSR “Demokritos”, using the 3 H(d,n) 4 He reaction. In addition, theoretical calculations with the EMPIRE code have been performed, in order to find a suitable model for the description of the experimental data of the present work along with the data from literature.
